Is CYTS on Taobao reliable? Free travellers who want to travel abroad. Asking for information

Ask carefully not Taobao, but those big travel companies and tour groups? This thing, no matter how poor it is outside, we are usually frugal, but we can't play outside. It's better this way. Cheap and no good goods. This thing is very troublesome, and it will be difficult to deal with the problem then. If you want to be cheaper, you can always pay attention to those big companies. Sometimes they will send a delegation and take one or two people out, and the price will be very low. Will you seize this opportunity to go out? It's cheap and difficult.
