Hutou Cliff in Laizhou: Dig clams at 7:20. At 7: 20 this time, the sun went down and the weather was not hot. The Hutou Cliff Sea in Laizhou ebbs at 7:20, which is very suitable for catching the sea! The first month, the end of the month and the middle of the month belong to the spring tide of the lunar calendar. Because of the gravity of the moon, the seawater recedes far away, which is also suitable for catching the sea. After the seawater recedes, the sea goods brought by the seawater will stay on the beach, including clams.
