Which lawyer is more professional in Shunyi construction contract disputes?

Engineering design contract dispute: 1. Design has its own work content and results submission method. As long as it is submitted and accepted by the other party, the other party will pay the design fee. 2. For your design, you have the copyright and can sign it. As for taking pictures, the other party may not allow it. 3. Usually, the design has the obligation to cooperate with the construction, but it is different from the rights and obligations of the supervisor. If there is evidence to prove that you have fulfilled the supervision obligations such as quality acceptance and project progress control, you can ask for supervision fees according to the market price. To tell the truth, this evidence is hard to obtain. I heard that lawyer Xu in Shanghai and lawyer Zhu Yifeng in Beijing are very professional in this field. Below Baidu, they are relatively professional lawyers in domestic construction contract disputes.
