Zhao Yurou stared at Yang Tianfeng's actions like fishing, blinked her eyes and started laughing. Then she laughed loudly, falling on the chair with a smile, holding her stomach, and tears fell out of her eyes.

"Look, I knew this wouldn't work. It's so funny." Yang Tianfeng sat down dejectedly, "It's better to sing instead. If you sing a song, you'll be done."

After a long time, Zhao Yurou panted and sat upright, wiped her eyes, and said with a smile: "Sing, it's okay to sing, I sing, what are I singing, what are you singing?"

"To reflect patriotism, it must be simple and easy to learn. Well, let me think about it." Yang Tianfeng touched his chin and began to think...

"We all have a home called China. There are many brothers and sisters, and the scenery is also good. There are two dragons in the house, namely the Yangtze River and the Yellow River. There are also Mount Everest, which is the highest hillside..." After singing a few times, Zhao Yurou was satisfied. She hummed back to the dormitory with the paper that was lyrics, preparing to clean up and attend the party.

As soon as the door opened, Hao Jiaqi walked in with a frown, gently stroked her stomach, as if she was very uncomfortable.

"Jiaqi, what's wrong with you? Your stomach is uncomfortable?" Zhao Yurou asked with concern.

"Well, I've been holding it in for a long time just now, and my stomach hurts a little." Hao Jiaqi grinned but smiled.

"I still laugh when I feel stomachache." Zhao Yurou quickly poured hot water.

"Miss Hua, don't run away, Zhao Yurou, see where you run!" Hao Jiaqi suddenly opened her teeth and claws and learned Yang Tianfeng's movements, shouting in her mouth: "The sky is made of quilts, the ground is made of beds, and I will give birth to a fat baby next year. Yurou, just follow me!"

Zhao Yurou was stunned for a moment, her face turned red, and she became angry, and she stepped forward and beat her, "Smilion Jiaqi, Lan Jiaqi, eavesdropping on others' words and peeking at others' acting."

"Hahahaha, fight, fight, I'm so suffocating, I can't do it anymore, let me laugh enough, I'm so happy, hahahaha..." Hao Jiaqi hugged her head with both hands and fell on the chair and laughed happily.

Henan people naturally have a special liking for Henan opera. Although they do not have the deep foundation of the characters on the Bangzi stage, they cannot sing the sonorous and grandeur of their hometown operas, with moderate elegance and smooth speech, they have been immersed for many years and can hum a few words casually, and they feel quite beautiful.

In an era of extreme material shortage, cultural life seems to be far better than the need for food and clothing. Festive festivals, temple fairs, and markets are indispensable for the lively scene of "singing big dramas".

The art troupe has now broken away from the constraints of singing traditional operas and has added some actors. The program is also rich and colorful, making people feel novel. Here are Henan Bangzi, Shandong Qinshu, Shanxi Bangzi, Hebei Old Tunes, and Northeast Yangge. It is all in one place, which fully demonstrates the colorful colors from all over the motherland, and is also to adapt to the needs of soldiers in the army from all over the world.

Sometimes young people applaud excitedly and enthusiastically, and sometimes they can't help laughing, and there is a kind of spiritual satisfaction that they have never felt before.

Other programs are also very exciting, and Zhao Yurou's "Big China" and Zhao Yuqing's "The Great Wall" received endless applause.

Both sisters are good-looking and have good voices. Yang Tianfeng sat in the front row and made an evaluation in his heart.

The party is coming to an end, and the finale is the chorus "Faithful Service to the Country".

"The history of China has been thousands of years, and there are countless heroes and heroes, and generations of loyalty and loyalty to serve the country for generations. The male actor first recited with a low and vigorous voice, and then blew out the passionate and loud singing.

"...Wolf smoke rises and mountains look north, dragons rise and roll up and horses neigh the sword energy is like frost, hearts are like the vast water of the Yellow River, who can fight each other in twenty years? I hate and desire to be crazy and swords, how many loyal souls are buried in other places. Why do you regret the death of your family and country? I can't bear to sigh and sigh and feel speechless. The horse's hooves go south and people look north, and people look north and grass is green and yellow dust is flying. I am willing to defend the territory and open the border again. China wants to congratulate all directions..."

"Sing it again, sing it again." This was the first time that young people like Zhao Yuqing heard this song. Their cultural level was more likely to resonate with them. They couldn't help but stand up and clamor, and their voices changed in excitement.

The singing started again, and everyone had already stood up, clapping, excited, excited, wept, sighing... His mouth opened and closed, humming clumsyly.

At this moment, Yang Tianfeng felt a huge stream of sound and passion surging in his blood, and he also sang along. Let the Japanese devils tremble in the heroic and heroic songs, howling under the Chinese flesh and blood Great Wall. I am not fighting alone, but I am following thousands of people to devote myself to the country!

Many years later, when a young man who participated in this entertainment party mentioned this unforgettable party, he wrote: At that time, I felt that blood was rushing to his head and his whole body was hot. It seemed that only by shouting and singing wildly could we vent all the passion. We held hands and danced around the fire, sang, and then held burning wooden sticks to march torches... The next day, few people who spoke normally were smiling at the duck voice.

…………………

The sky is blue and white clouds, the weather is clear, and two planes are soaring in the air.

Yang Tianfeng put down the telescope, then reached down the sunglasses placed on his forehead, and communicated with the pilot and technicians next to him with a smile.

Looking back at history, it can be seen that China's aviation industry did not start late. In 1911, China owned self-made aircraft, earlier than Russia, Germany and other countries, only after the United States, Britain and France. China made its first aircraft in 1914, and at that time, there were only a handful of countries in the world that could build aircraft.

This is because in the United States, Chinese experts who have mastered aviation engineering technology in Europe have returned to China to serve, so that Chinese-made aircraft can go beyond the initial stage of exploration and have a higher starting point. For example, Feng Ru, Pan Shizhong, Ba Yumao, Wang Zhu, Yang Xianyi and others are all first-class professionals who returned from countries such as the United States, Britain, and France.

Subsequently, under the promotion of "Aviation Save the Country", China's aviation engineering education developed rapidly during the Republic of China period from nothing to something. In 1934, the National Government held an aviation technology meeting and decided to assist various universities in establishing departments of aeronautical engineering. In the same year, Shanghai Jiaotong University founded the Department of Aeronautical Engineering, and Tsinghua University established the aviation group in the Department of Mechanical Engineering. In 1935, Central University and Beiyang University also established the department of aeronautical engineering. Later, Zhejiang University and many other universities established departments of aeronautical engineering.

A large number of young students actively applied for the Department of Aviation Engineering with the ideal of "saving the country through aviation". Chinese universities trained outstanding aviation scientific and technological talents such as Qian Xuesen, Guo Yonghuai, Qian Weichang, Shen Yuan, Wu Zhonghua, and Lu Shijia, which became a valuable asset of the country.

Despite this, during the Republic of China period, China's aviation industry was basically in the trial production or small-scale production stage for 20 or 30 years, and did not build an independent aviation industry system. The foundation was extremely weak and the quality of the aircraft it was manufactured was not good enough.

In contrast, Japan developed its aviation industry a little later than China. In 1916, Japan established its first aviation factory, but it built a strong aviation industry system within 20 years and armed the Japanese Air Force with its own-made aircraft. When Japan invaded China, its air force had an overwhelming advantage over the Chinese Air Force and had completely mastered air supremacy. The "zero" aircraft designed and manufactured by Japan was an excellent model in World War II, and once became the best fighter in the world.

The direct reason why China and Japan have such a big gap in aviation industries is that China does not have the industrial foundation on which the aviation industry relies on to develop - there is no precision machinery industry, no smelting and processing industry of special steel and aluminum. China's aircraft factories must import "upstream" products (metal materials, aircraft parts) of the aviation industry in order to maintain production.

After the outbreak of the Japanese war of aggression against China, China was blocked by Japan and its production was unsustainable. On the contrary, Japan has a good foundation for the metallurgical industry and the machinery industry. The "zero" aircraft uses a new superhard aluminum alloy developed by Sumitomo Metal Industry Company to have excellent performance.

In the case of a weak industrial foundation in China, if the government makes unified plans for the aviation industry and makes a reasonable division of labor, it can also enhance the independence and autonomy of the aviation industry and improve the production efficiency of aviation factories.

However, at that time, the government invested in the establishment of factories and set up factories without division of labor and cooperation, and each of them was in charge of their own affairs. There was no scientific plan for each factory to build aircraft, either imitating the United States, or imitating the Soviet Union or France. There was no further research on aircraft designed by itself, and it was improved.

Therefore, the aircraft made by various factories are diverse and do not have standard parts that are universally used in the country. In this way, the national aviation industry is a mess and cannot form a synergy, and the functions of the aviation factory will be greatly reduced.

Despite this, the intelligence of the Chinese cannot be denied, and the power that this intelligence bursts out under the cultivation of the right soil is amazing.

Through the Central Aviation Commission, through the Military Control Commission, and through its own recruitment and recruitment, aviation technicians who came to the base gradually formed a group.

Whether it is the original Hongqiao Aviation Factory, the Nanjing Capital Aviation Factory, the Hangzhou Aircraft Manufacturing Factory, the Dading Engine Factory, or the Nanyang mechanics, under the integrated guidance of Yang Tianfeng, this aviation technical group was finally established and began to learn, master the information Yang Tianfeng brought out, and also carried out practical production and manufacturing.

In addition to the repair and modified Type 94 two-seater reconnaissance aircraft that are flying in the air now, there is also a super-powered *************. The pilot is from the Air Force Sergeant School and has considerable flight experience.

Needless to mention the Type 94 two-seater reconnaissance aircraft, there was no change in anything except for dismantling the original weapons and equipment and installing two 12.7mm heavy machine guns that had just been copied from the Soviet NNSV machine guns.

Soviet NNSV machine guns widely used stamping and riveting assembly processes, which not only simplified the structure, but also reduced the weight of the entire gun, had better production performance, and higher shooting accuracy and reliability.
