As everyone in the industry knows, in fact, the cost of bidding agents is relatively low, and qualified bidding agents are living well. This is a monopoly industry, which can also be said to be profiteering. For example, Huadian Group and all its subordinate power plants are represented by Huadian Tendering Company, and many projects in the power industry are represented by China Power Investment Corporation. It is difficult for other units to represent them, but it is just a monopoly of resources.
