Hello. I invested money into a shop. The agreement didn't say I have to work for the shop. Now I'm working in the shop 6-7days a week. I don't want to do it anymore. However, the employer won't let me go, also he's holding my money. I'm afraid he's not going to give me my money back. I lost the receipt and the contract is in Chinese. If I quit, can I get money back under contract law?
