First of all, the builder's certificate is almost worthless. With or without background, you must be modest when you first arrive at the construction site. The implication is that unless you are not an architecture major, you can't read the drawings. The learning process in any industry must be from shallow to deep. You must first find a good master at the construction site. On the one hand, you should be smart and humble when dealing with your host, and on the other hand, you should be diligent and housekeeping in your life. It is necessary to respect teachers. Walking on two legs, one is to ask the master from the shallow to the deep according to his specialty, and the other is to buy some books on architecture frequently, and what tools are needed, what to do, how to do it, and what is qualified according to the construction situation on site. Each step of construction has its corresponding construction specifications and atlas to guide the construction, and drawings must be a compulsory course. First build, then construct, and then carry out construction in combination with corresponding projects such as hydropower.
