In the past, people were prone to lice because of poor sanitation. Gently rubbing the head with a grate is mainly used to scrape off dandruff and lice hidden in the hair, and also plays a role in massaging the scalp, relaxing muscles and activating collaterals. Modern people use combs, mostly for massaging the scalp. With the improvement of social living standards, the practical function of grates has gradually lost, and modern people use them for collection.

history
Zeng's grate in Tongchepu Village, Pu 'an Town, Kaijiang County is famous both inside and outside the province, and it is an ancestral handicraft of the local Zeng family. The ancestors of this family migrated from Xiaogan Township, Macheng County, Huguang in the early Qing Dynasty, leaving jobs and paving the land. Its grandfathers are good at producing perforated strainer, with unique technology, elegant shape and durability, which are widely welcomed in various markets and become big brands.
This family has been doing this for generations, and the craftsmanship is only passed on to the same family, not to others. In order to feel the kindness of their ancestors, future generations take the 23rd day of the first month, that is, the birthday of their ancestors, as a day of sacrifice and get together every year.
