What are the unique folk customs in Henan?

The seventh day of the seventh lunar month is a traditional festival of the Han nationality. Because the main participants in this day's activities are girls, the content of the festival activities is mainly begging skills, so people call this day "begging skills festival" or "girls' day". The custom of begging for cleverness in Xinxiang, Henan Province is that every year on the sixth night of the seventh lunar month, seven unmarried local girls form a group (according to the number of "Chinese Valentine's Day"), each of whom exchanges things for a face and prepares offerings for the Weaver Girl. Someone wants to buy seven kinds of melons and fruits, such as grapes, pomegranates, watermelons, dates and peaches, bake seven steamed buns with oil or sugar, make seven bowls of small jiaozi and make seven bowls of noodle soup. In addition, seven big jiaozi will be packaged separately. Dumpling stuffing is made of seven kinds of vegetables, and there are seven kinds of things made of flour, such as needles, looms, flower hammers, spindles, scissors, garlic cloves or abacus. These seven things should represent the wishes of seven girls.
