The sleeve armor of the original body pill and the two "ebony boards" and "dove tail boards" on the chest are not deformed. It is mainly composed of shoulder straps and high buckles, main chest plate and bulletproof vest, as well as grass pleats and diamond plates below the waist. It's much easier to add the left rib than the big armor.

In the past, it was often confused with abdominal volume, especially upper abdominal volume. In fact, the main difference between the two is that the belly roll is tied on the left side, while the belly roll is tied at the back. There are rules for the number of nails in trunk pills, generally two in front, three in back, four in long side and four in broken grass.

In the paintings in Heian period, we can see a warrior figure wearing a bucket pill: wearing a star pocket or Ebush but not standing, wearing a bucket pill, with a rough cage hand on his wrist, bare legs, no trousers, no shin scarf and bare feet. These characters are followers of knights on horseback, that is, the later light-footed class. When the tube pill first appeared, bamboo and leather were used as light clothes, which were specially used by barefoot lower warriors. Most of them are fake and inferior products. In the Kamakura era, some master soldiers also used barreled pills in pursuit of lightness. Of course, their equipment is different from ordinary pawns: shovel-shaped front star pocket, exquisite barrel pills, armbands, leather cage hands, pawns and leather stacks-most importantly, they ride horses.
