Is the socket in the hotel the same as that in China when traveling to Thailand?

The Volt in Thailand is the same as that in China, but there are only two plugs on the wall in Thailand, both round head and flat head can be used, but there will be three plugs for sale. If you buy a three-plug electrical appliance in Thailand, it will definitely be equipped with a three-to-two conversion plug, and most of the three plugs in Thailand are straight plugs or three plugs, and there are fewer oblique plugs.
