Qing, I know this company. The company has been really busy recently, and has received many orders, especially for the production of this piece, and there is a shortage of personnel. You may be busy expanding again, so sometimes it is reasonable not to take care of you in time. It would be a good thing if it was seen by other companies. If you want to go to Mirak, it doesn't matter even if you sign a contract. As long as you explain to the company where the contract is located one month in advance, they will not let you go.
