The intersection of Yellow River water and blue sea water is quite spectacular. The Yellow River has a large amount of sediment and extends towards the sea 2.2km every year. It goes to the sea at the speed of a football field area every day, with the annual land making of near 20,000mu. The river and sea intersection is a sky spectacle, where the yellow river water and blue sea water blend and collide every day. However, it does not mean that you can see it every time, because it needs three prerequisites:
1. The amount of water: the Yellow River should have moderate water amount, too large or too small will have risks, which is insecure.
2. The amount of sediment: if the Yellow River has low sediment content, the yellow and blue will not have clear distinction.
3. Tide: the tide is the best in flood tide, because the sea water will struggle to withstand the Yellow River water in rising tide and the scene is particularly spectacular. Of course, there is a certain law in the tide rising and recession. It occurs at 6:00am and 8:00pm in the 1st and 15th day of each month in lunar calendar and follows the sequence of delaying 46 minutes every day.
