I am very pleased that there are tourists to go to the 401 cave to play. I participated in the survey throughout this pit. Survey in the summer of 1970, and construction began in Xiling on June 18, 1971. It was opened in September 1972. It was originally used as the front line headquarters of Zhejiang Province. The command center is the higher place in the south space. The protective door is anti-atomic bomb. The construction unit is called Unit 70, 71, 72 and 73 of Unit 6418. The main officer is the leader of the White Battalion, Wenzhou, a very good person.

It's okay to look outside, the scenery is good all the way, the smell in the cave is very heavy and the ventilation is not good, and the smell in the cave needs to be improved.

It's really a good place here, 401 cave sky, here you can see a lot of outside sky bursting things, there is a feeling of paradise, anyway, I like it here very much, welcome everyone to come here to see.

It's cool and authentic. There's a bat group viewing area in it. It's true.

Four O one hole day, thirty yuan ticket, cost-effective, bus inconvenience, the surrounding facilities are not complete, such as education base, thirty yuan ticket is too expensive. Unworthy
