Children like the history of the pre-Qin Dynasty in the Warring States, the holiday brings Hanguguan, the knowledge is OK, just read a lot in the book, this time I feel it on the ground, and I have gained a lot of knowledge about the moral scriptures. I feel that the scenic spot has not been developed well, and there are many stories around Hanguguan, but there are Laozi from beginning to end. The 75 tickets are very expensive, and I feel that 40-50 yuan is enough.
