As the name implies, "tube wiping" protects the chest at the front, and when put on, "it can cover the chest at the top and the abdomen at the bottom", so the whole chest and abdomen are covered, so it is also called "tube wiping". There is also a slightly longer "wrapped belly", which laid the foundation for China's belly pocket in Qing Dynasty. The tube top is tied at the back with buttons or straps.

After wearing the "tube wipe", the whole chest and abdomen are covered, so it is also called "tube wipe". Ordinary people use cotton products, commonly known as homespun, and nobles use silk products with embroidery on them. There are different forms of sheets and clips. This kind of pipe roof is often found in archaeological excavations. For example, a piece unearthed from a female tomb in Fuzhou, Fujian, is double-layered, with plain silk outside and a small amount of silk wool inside, which is 55 cm long and 40 cm wide; At the top of the tube and the upper end of the tube waist, there are tie ribbons. Back in the 62nd session of Jin Ping Mei, Li Pinger was seriously ill. "His face hasn't changed, and his body is still slightly warm, but he died, and he has a HongLing tube top on his body." In A Dream of Red Mansions, he wrote three sets of makeup bundles: "He wore a little red coat, which was half hidden, deliberately revealing a lush tube top and a trace of snow milk." Everything is about this kind of underwear.

In the Song Dynasty, wiping the chest and wrapping the abdomen were two kinds of underwear, not two names of one kind of underwear. In terms of shape, it is generally a long belly and a short tube top.
