Power of attorney for engineering investigation

If the client makes any rights and interests that violate national laws, the client has the right to terminate the entrustment agreement. In our experience, there are more and more transactions using power of attorney. I believe many friends are very upset about writing a power of attorney. The following is the power of attorney for engineering investigation collected by me for reference only. Let's have a look.
