2. After the bid opening is over and the bid evaluation stage is entered, the tenderee can no longer take the initiative to question. At this time, if the judges question the bidding documents, the bidder can answer the judges' questions in writing by replying to the questions.
3. During the period from the receipt of the tender documents to the confirmation and publicity of the successful candidate, if the tenderee finds any irregularities in the tender procedure, he may raise questions or complaints to the tenderee in writing.
