Because I only have three months, I still have a lot of stress in my studies.

The cadre class basically takes classroom learning every morning, and instructors from various subjects teach students. Among them, the instructors who teach "guerrilla tactics" and "guerrilla political worker" are major general-level instructors invited by Hu Zongnan from the staff class of Huangpu 7th Branch.

"Infantry Practice" and other teaching materials are based on the Whampoa Military Academy's textbooks, while the two courses of "guerrilla tactics" and "guerrilla politics" are newly established courses. The textbooks are translated by the Soviet Union and then combined with the tactical ideas of the Eighth Route Army. Especially the "guerrilla tactics" course, because the lectures will tell many examples of the Eighth Route Army's guerrilla warfare, and these vivid examples are particularly vivid, so they are most popular among students.

The homework time is basically every afternoon. This kind of homework is divided into two categories. One is homework on paper, that is, the instructor sets questions and students answer on paper; the other is homework on the playground, which is to conduct guerrilla tactical confrontation through exercises, or conduct field services, or perform blasting homework.

The students were not at peace at night because there was another course called "night education", and the students often had to conduct exercises of night attacks.

The cadre class did not relax the ideological education of students. Each squadron set up a political instructor to supervise the students' political thoughts at any time. At the same time, each student also distributed books such as "The Prime Minister's Past Teachings", "The President's Words and Deeds", but these books were not taught by instructors, but were allowed to be referenced at all times.

The students study six days a week and only have one day to rest on Sundays.

Cuihua Mountain is a famous scenic spot. Now the training class is at the foot of the mountain, so Li Qinglin naturally won’t miss the opportunity to visit.

Cuihua Mountain has rich cultural and historical landscapes, including Taiyi Temple, cliff carving forest, Emperor Wu of Han’s visit to Taiyi Zhenren Taoist temple, etc. Cuihua Mountain also has natural landscapes that are not available in other places, including large gravels formed by the collapse of the mountain, ice caves and wind tunnels, dangerous and magnificent cliffs of the residual peaks, and mountain dams formed by the collapsed dam.

Below a cliff there is a large flat stone wall with sixteen big words written on it: "Born from reason, good at fighting, hardship, and finally morality."

These sixteen characters are the motto of Huangpu Branch 7. I don’t know who wrote it. From the perspective of calligraphy, they are not considered top-notch, but their brushwork is vigorous and heroic, and they are very military. Several years later, Li Qinglin learned from a friend that these sixteen characters were carved on a stone wall and became a famous cliff carving in Cuihua Mountain.

Most of the students in the Youkara class were officers and political workers drawn from military forces and local armed forces in various countries north of the Yangtze River. The highest rank was a major general, the lowest rank was a captain, and the most were school-level officers. These officers came from all over the country and knew that they only had three months of study. After graduation, they had to go to various places to fight guerrilla warfare. In order to get the support and care of alumni in the future, these officers invited guests to dinner, hoping to establish good relations with their classmates.

Li Qinglin also participated in several such activities, but he was not keen on establishing relationships with his classmates because he was concerned about the business of the Liyuan dyeing workshop, so he ran to Liyuan Village whenever he had time.

At Liyuan Dyeing Workshop, Li Qinglin witnessed the entire process of hand-made blue printing and dyeing cloth.

Before the official printing and dyeing, the masters from Suhu prepared the flower version first.

The flower plate is the carved cardboard used for printing. It is usually made of three to five layers of paper. The paper used is two to three layers of Guiyang vellum or mulberry vellum paper and one to two layers of Korean paper. Craftsmen use homemade flour paste to frame it. After it is dried, a layer of cooked tung oil is applied. After the tung oil is dried, it forms kraft paper to be flattened.

The patterns can be designed temporarily, or the presbyopia version can be used to make a substitute. The substitute version is to cover the presbyopia version flat on the tung oil kraft paper to be carved, and use a broom to dip a little pigment to replace the original version.

After the patterns are basically determined, three to four layers of kraft paper are nailed together and used a homemade carving knife to carve. The quality of the blue cloth printing pattern depends entirely on the design and engraving process of the pattern.

The flower plates after carving need to be further processed. The back of the flower plates should be polished and smoothed with smooth pebbles, then brushed with tung oil and reinforced and then dried. After two or three times, the flower plates are sorted and packed for printing and dyeing.

Before formal printing and dyeing, you have to choose fabrics. Only fine cloths can dye blue printed fabrics. Ordinary coarse cloths will be dyed with pure blue cloth. Before scraping, you need to sprinkle the white cloth with water and roll the cloth. This is to moisten the dry cloth, and moisturize it to allow the white cloth to better absorb the dye slurry.

The next step is to scrape the pulp. Scraping the pulp means using the flower plate to scrape it on the white cloth to prevent dyeing.

Anti-dying pulp is made by craftsmen themselves, and is made of lime and soybean powder. However, some patterns also require the use of glutinous rice flour and lime powder to make anti-dying pulp. The pulp is very particular, the thickness should be moderately thick and viscous, and the finer the soybean powder, the more thorough the pulp is, the better the stickiness, and the better the effect of the printed blue printed cloth.

After everything is ready, the craftsmen spread the white cloth flat on the large chopping board, covered the prepared pattern on the white cloth, and then used a scraper to scrape the anti-dyed slurry on the flower plate. Where there are hollow patterns, the anti-dyed agent will leak on the white cloth, and the place where there are printing and dyeing will still be white, while where there are no hollow patterns will be completely dyed blue.

The grey cloth that has been scraped with slurry will take two days to dry. After the mortar is dried, it can only be put into the dyeing tank for dyeing.

The dye used in blue printed cloth is blue indigo. Blue indigo is generally made of blue grass. There are many types of blue grass, and the root of the most commonly used blue grass is the famous Chinese medicine isatis root.

The craftsmen poured blue indigo into a small tank and stirred it with lime, rice wine and appropriate amount of water to turn the blue indigo water yellow and indigo foam appeared on the water surface. This indigo foam is commonly known as "indigo flower". At this time, you can pour the blue indigo water in the small tank into a large tank for later use.

After the blue starch water in the large tank is ready, put the bamboo basket into the large tank. Then open the scraped cloth slurry and soak it in the water. After the slurry on the cloth is soaked and soft, you can go down to the tank to dye.

Twenty minutes after laying the dyeing tank, take it out and ventilate, and the time is about thirty minutes. At this time, you must constantly turn the cloth surface to make it oxidize evenly, so that the blue dyed finally looks bright and beautiful. The cloth cannot achieve the ideal effect when it is put into the tank at one time, and it must be five or six or even eight times to get the ideal blue.

After the dyed cloth is dried, it is also necessary to scrape off the anti-dyed slurry attached to the blue cloth, which is also called "scraping ash". After scraping the anti-dyed slurry, the original color will be revealed, while the area without the mortar will be dyed blue, so various exquisite patterns appear on the cloth...
