My name is Hou Xiyun，is a worker in the second production shift of the installation team of Hanjiawan Coal Company。My squad leader is Cao Yanpeng，He is not tall，Pretty face，Speak seriously，Is a dedicated young student。

Remember when the 214201 intelligent fully mechanized mining working face equipment will be withdrawn in 2021，The equipment train has moved out of the maintenance lane，But the cable near the coal wall，Stuck firmly on the deformed steel hook，There is only a small gap between the two trains。Looking at everyone in a hurry, there is nothing we can do，The skinny Cao Yanpeng stood quickly in the gap，Use the arm gap，The cable that will get stuck in the pipe hook a little bit，Pick them off one by one。Soon，The beads of sweat on his forehead fell down。The whole class comes down，He never shouted tired。Under his inspiration，Everyone rushed forward，Clean out the heavy and lengthy cables one by one...

One more time，Our class is responsible for the task of reinforcing and supporting the lanes of the 214201 fully mechanized mining face。Although the technical requirements for support have been issued，But in actual work，Because the coal wall is under greater stress，Part of the coal wall is loose and leaking，The installed anchor plate is not fastened properly，Cao Yanpeng, a serious person, took the initiative to pick up the testing tool，Test one by one，I am afraid that the quality of support may not be up to standard...

There are many more "serious" things like this，He often tells everyone at the pre-class meeting: "Go to the post and be assured，Do your job with ease。”Unknowingly，We have been working together for eight years，Every time we encounter urgent, difficult and dangerous tasks，Cao Yanpeng always rushes to the front，Set an example to everyone。I believe under his leadership，Our class will not be afraid of difficulties，All the way forward。(Author: Hou Xiyun Editor: Wang Yu)
