Does the person in charge of the bidding project need 3 months of social security and 2 months of employment before bidding?

The person in charge of the bidding project needs social security for 3 months, and can't bid only for 2 months. Generally, the tender documents will require the bidder to provide the social security payment certificate of the employees in the company for the first three months from the date of bidding, and the bidder who bids for this project will buy social security for three months. General social security can not meet the requirements of the last three months and only two months of employment, so the person in charge of the bidding project needs three months of social security, and bidding projects are not allowed after only two months of employment.
