Can I book my own hotel for my business trip now?

Tourism is a personal entertainment activity, not a business trip. You can't book your own hotel without going on a business trip. The approval and reimbursement of personal leave will be completed on the official platform. No business trip, no official residence. If used, it is suspected of travel fraud. This is not right. If the unit finds out, it will make corresponding treatment and deduct the business expenses you use for the official residence, so you can't use the official residence.
