Next week going back to my home country urgently need to sublet my bedroom with an ensuite bathroom. Open to negotiation!

Sure, here's the translation: "Dear XiaoHongShu, please help me find a tenant for my child. If we don't find one by next week, we might lose the deposit. It's a 2-bedroom apartment with ensuite bathroom, and the roommate is a male student from UNSW. We need someone to move in ASAP, and the lease goes until the end of July. The apartment is fully furnished with all necessary appliances. There are plenty of Chinese supermarkets and restaurants downstairs, making life convenient, and it's within walking distance to the station."
