Tidal variation law: Due to the gravitational effect of the sun and the moon on the earth, most coastal areas in China have tidal phenomena of seawater fluctuation twice day and night. Every month, the first day to the fifth day of the lunar calendar (or the sixteenth to twentieth day of the lunar calendar) is the spring tide (called "the flood season" locally); The sixth to twelfth day of the sixth lunar month (or the 21st to 25th lunar month) is a small tide (called "dead tide" locally); The ninth or 24th day is the minimum tide (called "the end of the dead flood season" by local people). The tidal time is delayed by about 45 minutes every day, and so on.
