Han started from scratch.

1at the end of 945, we marched into the northeast, and the central authorities transferred a number of military cadres from Yan' an and various liberated areas to work in the northeast. They collected some mechanical equipment in Shenyang, Anshan, Tonghua and other cities, and planned to establish a military base in Tonghua. /kloc-in the summer of 0/946, Kuomintang troops attacked Nanman on a large scale and occupied Tonghua and Dandong. Han, then Minister of Military Industry of Northeast China, led everyone to transport machinery and materials to North Korea, and also recruited a group of workers and technicians along the way. At the end of July, they arrived in Hunchun, a small town at the junction of China, North Korea and the Soviet Union. Hunchun is an intermountain basin, where Tumen River and Hunchun River meet, facing North Korea across the river, with convenient transportation. It's only 30 miles away from the Soviet border and North Korea 10, with roads and railways. Everyone thinks that the hidden conditions here are good, and the resources, electricity and transportation conditions are also good. Decided to build a northeast military base here.

According to the existing conditions, Han decided to concentrate on producing bullets, grenades and mortars urgently needed by the army. The technology of gun production is too complicated to be realized in a short time. They first built a machine factory, a bullet factory, a Grenade factory, an ironmaking factory, a pharmaceutical factory and a timber factory in Hunchun. These six factories are the earliest military bases in the Northeast Liberated Area.

The bullet factory was established on the basis of the factory left by the Japanese, on the outskirts of Yanji. There used to be more than 300 machines with a daily output of 400,000 rounds. After War of Resistance against Japanese Aggression, the factory was destroyed and the machine was stolen, leaving little. The Korean organization moved the remaining factory to Hunchun, equipped with 14 bullet machine, 3 million semi-finished warheads, 20 million empty shells and more than 20 Japanese skilled workers. After a month of intense installation and trial production, the first batch of bullets were produced in September. According to the statistics of the first month, * * * produced nearly 1.3 million rounds of third-class bullets. This is really a remarkable achievement.

After solving the problems of cadres, equipment and raw materials, the most important thing is the problem of workers and technicians. The workers and technicians in Hunchun Base come from China, North Korea and Japan, and there are many complicated political and policy issues. Military cadres spent a lot of effort and energy on ideological and political work, but there were only 240 workers at that time, and even fewer people really understood technology. Leaders attach great importance to anyone who has a skill and let them be the heads of production departments at all levels. Some of these skilled workers were brought from Anshan, Benxi and Tonghua, and some were recruited locally. Yu Zhenmi, the director of the bullet factory, is a hired mechanic and enjoys salary. He saw the cadres of the * * * production party in the supply system and doing everything at the front. They were moved, took the initiative to cancel their wages, ate the supply system like cadres, and have been doing well since they became section chiefs.

Due to the lack of middle and senior technicians, the military factory can only choose from the retained Japanese. In the military factory in Hunchun, the Japanese are all key technical jobs. For example, there are more than 60 Japanese in the Grenade factory, almost all of whom are in important technical positions. The head of the manufacturing department is a small capitalist who originally opened a factory in Japan. The US Air Force blew up his factory before coming to China to make a living. He is an expert in Grenade manufacturing technology. The main process of Grenade assembly is to attract firepower. The head of the Fine Drugs Unit is also a Japanese old man. He is stubborn in thought, but he works hard and is good at drawing fire. The assembly workers of refined medicine group are all Japanese.

Due to the difficulties and depression of life, these Japanese people often brew together to return to China and walk slowly. 1in August, 947, Japanese nationals were repatriated to China from the northeast. After the Japanese got the news, they held a secret meeting and wrote a slogan in the factory building: "We will go back to China, and you will go home!" Because of the language barrier, a lot of truth has been said, but the effect is very small. Cadres combine hard and soft, do not listen to advice and give orders, establish strict statistics in the workshop, praise those with high output every day, and criticize those with low output or poor quality. Severely criticize the activities of bad people at the conference and prohibit the rise of fascist ideas. The Japanese have a strong sense of obedience, so they won't make trouble.
