In which dynasty did the custom of putting needles in Chinese Valentine's Day prevail?

In the custom of Tanabata, putting needles to measure cleverness prevailed in Ming and Qing Dynasties.

China has the custom of throwing needles to test the dexterity, which is held on the seventh day of July every year. It is a variation of needlework custom in China on Valentine's Day, which originated from needlework and is different from needlework.

Prepare a washbasin for injection, put it in the yard, and pour "Yuanyang water", that is, mix the water taken during the day with the water taken at night. Spend the night in the open-air washbasin and water, and then the next day, that is, the seventh day of July, the sun shines during the day, and you can "try to be smart" at noon or afternoon.

It turned out that the water in the basin was exposed to the sun for a long time, and a thin film was faintly formed on the surface. So, take the lead (that is, sewing needle) and gently lay it flat on the water, so that the needle will not sink, and the needle shadow will appear underwater.

Festival customs of Qixi:

1. In rural areas of Zhejiang, it is popular to use washbasins to receive dew. Legend has it that the dew on Tanabata is the tears when cowherd and weaver girl meet. If you put it in your eyes and hands, it can make people agile.

2. On July 7th, the Seven Mothers' Meeting was called "Worship Seven Sisters" in Guangdong and "Worship Seven Mothers" in Fujian and Taiwan Province. Before the founding of New China, Tanabata was a grand festival for beautiful girls. In the old society, beautiful girls begged Qi Jie to teach her clever skills, but in fact, the so-called "begging for cleverness" was just "fighting cleverness".

3. "Put a needle on the moon" means that on the night of the seventh day of July, every family should clean the courtyard. Young women and girls must first bow down to Vega and pray for her to bless their intelligence. Then, they took out colorful silk threads and seven silver needles prepared in advance and put them on the moon. Whoever puts on seven stitches first indicates that she will become a skilled woman in the future.
