1966, the brigade organized personnel to support the construction of Lugu Canal in Yuehua Township. At that time, people didn't have enough to eat and didn't wear warm clothes. Who was willing to help others consciously? The leader of the brigade was puzzled, but 22-year-old Liu Dehui took the initiative to apply for support for canal repair. Under his drive and shadow, several young people in the village also stood up and signed up. Liu Dehui was absorbed as a glorious party member by the Party organization because of his outstanding performance in supporting the construction. From 1972 to 1986, with the trust of superior leaders and the support of villagers, Liu Dehui successively served as secretary of the Youth League branch, company commander of the militia, battalion commander and deputy secretary of the Party Committee of the brigade.

People of the older generation said that it was not easy to be an official in that era and that special period, and as long as you are an official, you have the qualification and reason to put on airs and talk about style. But Liu Dehui didn't. Driven by the cultivation of the organization, the concern of the leaders and the trust of the villagers, he threw himself into his work. He always thinks of the villagers, gives up his family to serve everyone, and wins the support and praise of the broad masses with the vanguard and exemplary role of * * and the benchmark image of grassroots leading cadres. Talking about the past, he said: "The leaders and villagers all believe in me and support me, so I will be a good parent." He said and did this for more than ten days.

In the sixties and seventies of last century, farming in rural areas was far from the application of science and technology and improved varieties, and the yield and quality of crops planted were very average. However, Liu Dehui, who loves learning and is well informed, put forward the idea and proposition of cultivating improved varieties and increasing production. He said, "At that time, I was a little leader, little party member. If I don't take the lead, who will? " ? ! "He immediately set up an agricultural technology team, led by him personally. First of all, one kind of rice produced in Xichang was mixed with another kind of rice produced abroad, so as to produce a high-yield and high-quality white rice. After the second scientific and technological planting, it is proved that the yield per mu of this glutinous rice has increased by nearly 200 kilograms on the original basis. Grain is sent to the grain depot, and the grain depot is also purchased at a price of one catty to one and a half jins because of its good quality. After the success of the experiment, large white rice was planted in the village 150 mu. He also passed the improved varieties to other production teams for planting, so that everyone could enjoy the sweetness of applying technology and improving varieties together.
