It is a custom in Tianjin to eat tangdui on the eve of the Chinese New Year. The most popular tangdui is made of hawthorn berry. Hawthorn berries have their seeds removed and are skewered on a thin bamboo stick, then dipped in hot syrup. When they turn cool, the stringed berries wrapped in crystal sugar look like beautiful stone beans pungently sweet and sour.

Sometimes, the hollowed hawthorn berries are filled with red bean paste, walnut and melon seeds. Today, in addition to hawthorn, a wide variety of tangdui has been developed, including water chestnut, tangerine, apple, pear and crab-apple, etc.
