"Singing Ha Festival" is the biggest traditional festival of Jing nationality. "Singing" is a Beijing dialect, which means "singing". Legend has it that during the Chen Dynasty in Vietnam, there was a singer who, in the name of teaching song and dance, mobilized the Jing people to resist the Chen Dynasty's rule in the Jing area and was deeply loved and admired by the Jing people. Later, people established hatred and built a temple to commemorate him.

At the same time, because of his melodious singing, he is deeply loved by people and praised by future generations. So singing once a year has become a festival for Beijingers.

The date of singing Ha Festival varies from place to place. Shu Wei and Wu Tong are on the 10th day of the sixth lunar month. It's the tenth day of August. The place to celebrate Ha Festival is Ha Ting. In every village where the Jing people live together, hatred is based on this. Hatred has a unique national style. It is made of the best wood and has a beautiful appearance.

Hatred is mainly used for singing. There are also statues and gods shared by the whole village, as well as memorial tablets of ancestors with different surnames.

Whenever Ha Festival is sung, Beijingers from all over the world, regardless of gender, old and young, will put on festive costumes and gather in front of Ha Ting to hold activities such as ancestor worship, greeting God, singing Ha, praying for a bumper harvest and animal prosperity.

Haha's songs are very rich in content and have a fixed song book. Hassan, three people showed up. Especially accompanied by piano, the two singers of "Mountain Heart" sang in turn. The whole process of singing Ha Festival can be roughly divided into several procedures: welcoming God, worshiping God, sitting and singing Ha, and sending God away, among which sitting and singing Ha is the most important part. "Singing" usually lasts for three days, singing and dancing all night.
