Can the standard open tender be "opened in advance"

There are only comprehensive evaluation method and lowest price method in the bidding method. For some areas now, the lottery is also used. For public bidding by drawing lots, it is not necessary to make bidding documents as long as 20 calendar days. In general, the tender documents can be completed in 3 to 5 days. The provisions of the Bidding Law shall be regarded as early bid opening. As the lottery method is a new bid evaluation method, the legal effect of the bidding method is relatively lagging behind. The bidding law follows the principle of "openness, fairness, justice, honesty and credibility", so the public bidding by lottery generally does not adopt mandatory early bid opening, but the legal person or authorized person signs the letter of commitment for early bid opening when all bidders are recognized, so as to ensure that the results caused by early bid opening are borne by themselves.
