Which province in China has the custom of throwing a handkerchief to invite relatives on the night of the Mid-Autumn Festival?

Some areas in Shandong Province have the custom of throwing a handkerchief to invite relatives on the night of the Mid-Autumn Festival.

On the night of the Mid-Autumn Festival, a colorful platform is set up in the square, which is decorated like a moon palace, with a jade rabbit and a laurel tree. Some unmarried girls dressed as Chang'e, after celebratory songs and dances, the girls will be some embroidered handkerchiefs of different colors thrown to the stage. If an audience member receives a handkerchief of the same color as the one in the hands of Chang'e, he or she can go on stage to receive a prize. When some unmarried young men return their handkerchiefs, if they are liked by Chang'e, they can give them a ring. Thereafter, the two sides can make friends with each other, and those who are in love with each other will be happy to tie the knot.
