The soul treasure of the country, the protection is too bad! From Gongyi Bus Station Unicom Building, take the tourist line to the entrance of the Grotto Temple. If you come by train, sit at the traffic hotel station behind the train station. Usually there are very few people, and the two caves that can be visited can be visited. The "post-Emperor cruise map" is in it. After seeing Yungang, Longmen, Maiji Mountain and other grottoes, you can see the most intact and rich sculptures of the most beautiful characters. Unfortunately, the protection measures are too poor, some of them have just been covered with glass baffles, most Buddha statues can touch with their hands without security measures, I don't know how long it will still exist! I hope that people who go can take care of it, don't touch it, don't turn on the flash, don't open the film.
