I can't. The Sanbei Shoal covers an area of about 500 square kilometers, and the outer edge of the shoal is silted northward. The beach can silte out100-150m every year. There are many mud snails, clams, yellow clams, sea melon seeds, sand crabs, crabs and tidal shrimps here, which can't be caught in the daytime. The most suitable time to catch crabs is the high tide, and in the evening.
