There is nothing wrong with traveling on May 1st, it is a lot of people, there is no way to do things. However, the overall environment is better than a few years ago. There are many interactions with small animals. The scenery is also very good. We changed to a new tour bus. We took the green No. 10 bus. The driver's part-time tour guide service was very thoughtful. The speech was very humorous and I explained a lot of animal-related knowledge to everyone. I was very happy to visit.
