San cát kiểu này phải làm một cái vỏ thứ của mấy a cát hút sang qua mới ngon chứ máy mạnh quá sang qua gần đầy cát lắng ko kịp nó trào ra ngoài hết rơn hao cát cực kì
They pump the sand from 1 boat to the other only onto 1 side and then they stop and pump the sand back to the other side of the boat to even it out. When pumping it from the 1st boat why not spread it evenly on the 2nd boat in the 1st place? It makes no sense. No wonder Vietnam is still a 3rd world country if that’s how everything is done there.
They tilt the boat to one side to get rid of the excess water, they kicked out the French and then the Americans before they could destroyed their country. Vietnam Number one country.
