Is it legal to draw lots to decide whether the short-listed bidder or the winning bidder is legal?

Telling the truth, determining the short-listed bidders and winning bidders by drawing lots may select enterprises with general qualifications, but as long as they operate openly, they can avoid human factors in bid evaluation and be fairer. What's more, to participate in the bidding, you need to have the corresponding qualifications first, which basically guarantees the strength of the selected enterprises. It should be said that it is feasible and legal.
