What does it mean for a girl to send me a Happy Tanabata?

Suggest that she likes you. Generally, if a girl has a lover, she will not wish others happiness on Tanabata, but only the person she likes, Tanabata. If you like her too, you can boldly tell her. If you don't like her, you can not reply, or you can definitely reply to her "I wish you find your one soon", and she will understand.

Valentine's Day in China is not only a festival to worship Seven Sisters, but also a festival of love. It is a comprehensive festival with the folk custom of "Cowherd and Weaver Girl" as the carrier, with the theme of blessing, begging and courtship, and women as the main body.

The "Cowherd and Weaver Girl" on Tanabata originated from people's worship of natural phenomena. In ancient times, planetariums were associated with geographical areas. This correspondence is called "dividing stars" in astronomy and "dividing fields" in geography. According to legend, on the seventh day of July every year, the Cowherd and the Weaver Girl will meet at the Magpie Bridge in the sky.
