I am engaged in construction project supervision. Suddenly my friend opened a bidding agency and wanted my help. What should I do?

Bidding is definitely more tiring than supervision, and it is much more tiring. Without a bid section, different construction schemes should be formulated according to the construction situation, and the material cost, temporary construction cost, labor cost, construction period, staffing and so on should be accounted. Unless you are willing to start from the leadership and spend three or two years from the foundation, the bidding agency is also busy at both ends of Party A and Party B, it is hard to say that it will give you a commission, but the extra money is definitely not as good as it is. You have been in charge for many years. I work in China Railway. I suggest you strive for the position of director. Another point is that it is much more difficult to follow your friends than to follow the supervision company.
