Why did Huangshan Reservoir stop bidding?

In 2020, the announcement of the termination of the bidding project of the preparation unit of the feasibility report on the construction and use of forest land for Huangshan Reservoir in Linyi City, the announcement of the termination of the bidding project of the preparation unit of resettlement planning, and the announcement of the termination of the bidding project of the preparation unit of environmental impact assessment report were released at the same time.

Judging from the logical relationship that the project must be submitted for approval before bidding, Huangshan Reservoir has completed the project.
