This is my first day in steemit, I am very happy to meet friends from all over the world， Because I am in mainland China, Because of the existence of firewalls， it is not so convenient for us to use the Internet.
Today is China's National Day holiday, seven days long, the whole country is in a happy and festive atmosphere, many people choose to travel, but in my opinion, it is not a good idea to go out when everyone chooses to travel, because there are too many Chinese and hot scenic spots are too crowded. So I did not choose to travel, but choose overtime, my job is to ensure the normal use of elevators. Because it's about everyone's daily life, haha !
This is the elevator that everyone uses on a daily basis, its control center, this is an elevator mainframe, does it look a little rudimentary?
This is its control cabinet, the motherboard is in here. This elevator can not run, there is a very strange failure, I suspect that the motherboard is broken! I'm going to try another motherboard。
With a new motherboard, the elevator will work properly，
Although the temperature is very high, also very tired, working for a few hours, but can solve the problem I still feel very happy,
It was dark,The street lamp is on, and I was going home。
A very fulfilling day, no matter which country you are in the world, I will bless you! Good night!
