What does Hainan tourism mean by zero negative ground connection?

That is, you didn't pay for all the expenses such as accommodation, scenic spot tickets and meals. At the tourist destination (Hainan). Of course you paid the travel agency, but the travel agency didn't pay the land agency! In this way, the money of the group club is earned.

Then the tour guide and the driver will buy the head from the ground agency at the cost of each head before receiving you, so that the ground agency will also earn the first part of the money.

In the end, drivers and tour guides who lose money will earn money, at least they will earn back the cost from tourists. The money earned later, except for the full-time tour guide sent by the tour group, will be given to the company, and then it can be divided with the driver. But how much can you earn except the cost (money for buying people's heads) Actually, it's pretty pathetic. The people at the bottom are the first to be blamed!

However, this phenomenon is really special in Hainan Island, not in every city.
