The most interesting thing in Beitang Ancient Town is the Beitang Riverbank.

Beitang is located at the northern end of Tanggu District, Tianjin City, with a quiet and quiet natural environment. It has been known as the "Hometown of Zeguo" since ancient times. In the early Qing Dynasty, it was already a famous fishing town in Tianjin, Beijing and Yidong.

The bank of the Beitang River is a shell embankment, and the mud on the river beach is knee-deep, which is suitable for shellfish aquatic reproduction.

In spring and autumn, clams, clams, and snails are readily available on the beach.

There are many kinds of microorganisms living in the mud, and a layer of butter forms after being burned by the hot sun.

When the tide rises, this layer of butter floats on the water and is a good bait for fish and shrimp.

Every year from the beginning of spring to light snow is the fishing season.

In spring, a large number of fish come to the Bohai Sea to feed. At this time, the seafood includes crucian carp, prawns, branch fish, etc.

During the Grain Rain season, some valuable commercial fish follow the warm current and swim back to the coast of the Bohai Sea to spawn, reaching their peak at the Summer Solstice. This is the fish flood season.

The seafood includes croaker, seabass, prawns, sea crabs, flat fish, and mackerel. Not only is the yield high, but the quality is also good, especially the prawns, which are large, fat, and delicious.
