Use simple and popular language to help explain the terms in bidding: pre-tender estimate (pre-tender estimate preparation and scoring standard), hanging bid, bid opening, open bid and hidden bid.

Pre-tender estimate: it is the price compiled by the tenderer himself or entrusted by a unit with relevant qualifications according to the target and related basis, and it is an expected price for the employer to bid.

Target score: the evaluation score of each tender made by the bid evaluation committee (or group) according to the pre-determined evaluation method, and then the winning bidder is recommended to the tenderer according to the evaluation score.

Never heard of hanging bids. Maybe it's a escort or something.

Bid Opening: the deadline, the scheduled place, the bid opening meeting attended by all bidders and the pre-tender estimate announced in the tender documents.

Bidding process: select bidding method (pre-tender price can be compiled, but pre-tender price cannot be set)-put on record-publish bidding announcement-prequalification (this link is not included in the invitation to bid)-organize site survey-Q&A meeting-sell the bid-prepare the bid by the bidder-open the bid (usually on the same day as the bid opening)-evaluate the bid-publish the bid-winning notice.
