Typha latifolia is a kind of wild vegetable widely grown in the southern water town of China. The tender part of the pseudostem (Pumou) and the tender part of the top of the underground stolon (grass bud) are edible, fresh and delicious. Mature stolons and shortened stems can be cooked or used as feed; Male pollen, commonly known as "Pollen Typhae", has medicinal and nourishing effects.
Pucao stick had another function in the 1960s and 1970s. The machines in the factory are all used as brushes to wipe off the grease on the machines, which is disposable. The biggest use is as a pillow core, called velvet. Before cotton was introduced to China, it was often used to make bedding or cotton-padded clothes. There is a joke that a "xianggong" went out to do business for several years. When he came home, he saw his youngest son (adopted son) wearing a thin coat and his eldest son shivering in a thick coat, so he taught his eldest son a lesson with a whip. Little did he know that Pu Rong was exposed inside the clothes. Look at the youngest son, his mind is full of silk cotton.
