Can I still get a refund after traveling to Beijing for nearly two days?

If you are joining a group, you can get a refund. The Tourism Law stipulates that if you have to cancel the group due to work, illness, etc., or because of poor reception by the travel agency or poor arrangements by the local pick-up agency. Reasons such as failure to meet the requirements, breach of travel contract, etc. All unspent attractions, meals, transportation and other expenses will be refunded. But if you want to cancel due to purely personal reasons, then whether to refund or not, and how much to refund will depend on your negotiation with the travel agency. The length of the refund, and whether it will be easy, will also depend on the outcome of your negotiation with the travel agency.
