Where is the ancient underwater city of Liaohuahai?

The ancient underwater city Polygonum flower sea is in Poyang Lake.

Polygonum cuspidatum is actually one of the most common wild flowers in Poyang Lake area, commonly known as "half-year grain".

Polygonum cuspidatum, about 10∽30 cm high, usually grows in wetlands near beaches, ditches and ponds, and often grows in pieces.

Every year from 65438+ 10 to 165438+ 10, after Poyang Lake recedes, Polygonum cuspidatum flowers will grow rapidly, forming a purple sea of flowers, and "Purple Poyang Lake" has become a place for photographers and tourists to chase.

In Yinshan, Duchang Dachang, Gutang Township and other waters next to Poyang Lake, patches of Polygonum cuspidatum flowers compete to bloom, dividing the vast wetland grassland into two, forming a flower belt that stretches for several kilometers, like a pink belt wrapped around Poyang Lake. Curved "small river ditch" flows quietly from Polygonum multiflorum, and green, red and water colors naturally form a charming landscape painting.

Tourists decorate it, take photos or camp, laugh in the warm sunshine and enjoy the flowers.
