How about China International Travel Service Shenzhen?

Junk International Travel Service, I took my mother there a while ago. I was a group traveler. The tour guide’s itinerary was completely different from what the customer service said when I placed the order. I stayed in a hotel on the first night and collected all my ID cards. You are forced to go shopping the next day and your ID card will be taken away. If you don’t buy anything, you won’t be given anything. From morning to afternoon, you will be consumed with everything from junk diamonds, decorations, chocolates to watches and department stores.

Some people were on a three-day trip and left directly in the afternoon of the second day. I was on a two-day trip and had a free trip after noon on the second day. I went to Tussauds Wax Museum until 3pm. The tour guide didn't let you go until half past three. It was already 4 o'clock when we arrived in Central. My mother had been shopping since she got up at 7 o'clock that morning, and her body couldn't bear it, so we planned to go back to Shenzhen, but we didn't use the tickets.

After I came back and complained to CITS, my attitude changed completely. It was very irritating. I will never consider CITS Shenzhen again.

This is my experience, for reference only, thank you.
