Excuse me, what is the six-color gift for engagement?

When engaged, the man gives the woman six colors of gifts for good luck: fish, meat (with three ribs), sugar, wine, tobacco and tea in pairs, and the gifts are wrapped in red thread, red paper and red cloth. As for clothes, jewelry money and dowry, both parties are free to negotiate. The woman took down the meat, returned the ribs to the man, and then both sides ate them together. When getting married, the man brings a red quilt, red slippers, a red washbasin, a red mirror, etc., and the woman packs jiaozi fried cakes for her son-in-law. In this process, both sides prepare some red envelopes, chocolates, cigarettes and so on to enliven the atmosphere.
