1, have a reunion dinner: Shanghainese pay special attention to the winter solstice, while ordinary citizens get together for a feast on the winter solstice night, full of a big table, chatting while eating, pushing a cup of tea, and having fun. Affection, friendship and love are connected and deepened between cups and pins. A year's knot in one's heart contradictions vanished unconsciously, and a year's estranged affection and indifferent friendship were renewed again.

2. Tangyuan: In the old days of Shanghai, there was a poem that said, "Every family makes glutinous rice balls, knowing that it is the winter solstice of the Ming Dynasty." Shanghainese are used to eating glutinous rice balls on the winter solstice to celebrate the arrival of the winter solstice. "Round" means "reunion" and "perfection", and eating dumplings on the winter solstice is also called "winter solstice group". There is a folk saying that "eating glutinous rice balls is one year older".

3. Flower cake: In the old days, in addition to glutinous rice balls, newly steamed flower cake was also an essential seasonal food for Shanghainese at the family banquet on the winter solstice. The flower cake is made of rice flour, bean flour, etc. as raw materials, fermented, and decorated with fruit capsules such as dates, chestnuts and almonds, and steamed with sugar.
