Excuse me, what is the significance of rocking the ball bidding? Isn't it luck?

From the basic legislative point of view of the Bidding Law, it is meaningless. The significance of bidding is to increase market competition, save procurement funds, and constantly ask bidding enterprises to improve their core competitiveness. Lottery bidding does not meet the purpose of bidding and is not conducive to market competition. However, we all know the national conditions of China, and the purpose of bidding is not to compete, but to bid. This is also a dilemma in the current bidding industry, which is difficult to change.
