Triangle Zongzi, the traditional name of the Han nationality, is a dietary custom of the Dragon Boat Festival. Since Pudong came into being, people have had the custom of making triangular zongzi, which has a history of 1000 years. Legend has it that people in Pudong found that pillow-shaped zongzi was easily pecked open by fish in the river during activities to commemorate Qu Yuan, so they invented triangular zongzi. It's too painful to steal zongzi because the fish's mouth touched the corner. Triangle zongzi has been passed down to this day and is called Pudong local zongzi. The tourists listened with relish.
