What are the common cheating tricks of travel agencies?

This is really too much. First of all, these low-cost tour groups usually take tourists to buy some so-called specialties, such as jade and jadeite. Many products are fake industrial raw materials, or are produced with inferior raw materials. But the selling price is very high. The other is to add an unplanned tourist attraction for you. For example, take you into a cave, but there is a waterfall in the cave that needs to be visited for an extra fee. Since we're all here, don't you go in and have a special look at the so-called first underground waterfall in Asia? If you want to visit, go in through this fork hole and pay tens of dollars! Then there is the so-called three-star hotel accommodation. Please note that maybe the name of that hotel is Samsung. Does this remind everyone of the Regent Hotel in Stephen Chow?

Look at the two pictures above Everyone is called regent. But the treatment is one in the sky and one in the ground.
