I went to Sanya on May Day, but I heard that going to Vietnam costs 300 yuan a day.

Just returned from a trip to Sanya, I only know that Hainan is a visa-free destination, which means that it was troublesome for foreigners to play visa-free before, but it is not as easy for China people to leave the country for 300 yuan. . . I strongly feel that 300 yuan is just a cover. There must be more than n places to pay then. Make it difficult for you to ride a tiger. . . It is more reliable to call authorities such as the Tourism Bureau.
