"Knowing that the winning bidder maliciously wins the bid at a low price" can be based on the following clause: "The bid evaluation committee may cancel the bidder's candidacy for winning the bid." Article 54 of the "Law on the Administration of Tendering and Tendering for Government Procurement of Goods and Services" Bid evaluation shall follow the following working procedures: (4) Recommend a list of candidate suppliers for winning the bid. The number of bid-winning candidate suppliers should be determined based on procurement needs, but the bid-winning candidate suppliers must be arranged in order. 1. If the lowest evaluated bid method is adopted, the bids shall be arranged in order from lowest to highest bid price. If the bids and quotations are the same, they will be arranged in order of technical indicators. If the bid evaluation committee believes that the lowest bid price or certain sub-item quotations of the top-ranked bid-winning candidate supplier are obviously unreasonable or lower than the cost, which may affect the quality of the goods and cannot perform the contract in good faith, it shall be required to submit a bid within the specified period. Provide written documents to explain and submit relevant supporting materials; otherwise, the bid evaluation committee can cancel the bidder's bid-winning candidate qualifications and replace it with the next-ranked bid-winning candidate supplier, and so on.
