It is very similar to something called pimple soup in the Northeast. When I went to the hotel, I changed my name to "Pearl Jade White Jade Soup". It is actually the kind where small pieces of noodles are cooked in a pot. Linhai Shuangping Wheat Shrimp is very delicious. It's famous. The one they use is made from old soup, which is very good.
It has nothing to do with shrimps. Many friends misunderstood it when they first came to Haihai. I was the same at first!
