The company organized a tour and said that it could not resign within six months after taking part in the tour. If you resign, you will deduct the travel expenses in full.

This is a contractual relationship between employees and the company. As the saying goes, "take money to help others eliminate disasters." Since you want to work in the company, you must abide by the company's regulations. If you don't want to, you must find a way to resign. It is a conditional welfare contract for your company to organize tourism. You took part in the tour and then resigned, which violated the provisions of the contract law on offer and the contract agreement. Although there is no penalty, it is reasonable to stipulate that you must return the toll. If you didn't take part in the tour at the beginning, you don't need subsidies. If no man is suitable, you can leave, and there is nothing to worry about. I suggest you finish your work for half a year before you go.
