I work in a construction company, so you'd better stay where you are, because the construction company is too busy. First of all, it is difficult for you to enter a construction company. Do you have any experience? Because the construction company's work is too technical, even the logistics personnel need some time to hone. Construction companies need a variety of skills, so there are many technicians, so many times there are not enough people, so personnel and logistics people often have to sort out statistical charts at the same time. The working speed of experienced and novice is far from each other. Another most important reason is that the construction company is very busy and the work is very trivial. It's hard for you to find time to study. You need to master their workflow and many other things before you can transfer to a construction company. How can you separate your mind from your study? So now stay where you are, add a few more QQ groups and ask in the group.
