What should the person in charge of receiving the letter fill in?

The person in charge of the letter of acceptance shall fill in the name of the winning bidder. The responsibility of the winning bidder is that the winning bidder shall be responsible to the tenderer for the subcontracted project. In subcontracted projects, bidding contract and subcontracts are two different legal relationships. The winning bidder shall bear all the responsibilities of the winning project to the tenderee, even if the subcontracted project is agreed in the contract or approved by the tenderee, the winning bidder shall not be exempted from the responsibilities. Because how to subcontract and who to subcontract are all decided by the winning bidder.
