Imagine yourself getting thirsty or hungry during a mountain climbing exercise and there is a convenience* store right beside you, offering food and drinks, how great is that?

Rock climbing lovers in Pingjiang, Hunan Province, don't have to imagine this. They can stop and get food and drinks at a convenience store built on a mountain cliff *at the Shiniuzhai scenic area. The Shiniuzhai scenic area is famous for cliffs, canyons and rocks. It is also known for its glass-bottom bridge, which is one of the longest and highest glass bridges in the world.

Song Huizhou, manager of the Shiniuzhai scenic area, said the two-square-meter convenience store there is built on a mountainside about 120 meters above the ground. It was first built in 2017 and opened a year later. It takes people nearly one-and-a-half hours to reach the top. Visitors coming to experience the rock climbing program are usually amateurs*, so they often get thirsty and hungry along the way. Then the local government decided to build the store as a refreshment center for them. The food and drinks at the store are carried by staff members who work there every day. The climbers are allowed to take one free bottle of water and pay if they want more. However, the prices are the same as those at common stores. The store opens at 8 am and closes at 5 pm. If there are not many customers, there is no cashier* at the store and visitors can scan* the QR code with their phones to pay for the food and drinks by themselves.
