荔枝采摘后为何要泡水？
Lychees are sweet and yummy, but they go bad very fast after picking. These days, many people worry when they see videos of wet lychees online. They think farmers put dirty water on them. But that is not true. Farmers use only clean, cold water.
Freshly (刚刚) picked lychees are warm. Cold water can cool them down quickly. This is a safe and easy way to keep them fresh for longer. There is nothing wrong with it.
With new ways and fast delivery (配送), fresh lychees can reach to many places. If you are worried, buy lychees from good shops to stay safe.
