It is recommended that the guidance after the cruise should be objective, do not guide the guests to go to the cave, and mark the time of the cave. After the cave comes out, the order of the sightseeing car and the instructions on the entrance of the core scenic spot should be strengthened. This is my feeling of revisiting Tianhetan after 9 years. The deduction point is basically a sightseeing car. It is not surprising to expand a circle of business districts, but it is necessary to focus on the core scenic spots to guide tourists.
