According to Weibo's inquiry. Com, dried longan with shell and core is called dried longan (dried longan). If the shell and core are removed, only the pulp is left, and dried longan is called longan (dried longan).

Fresh longan cannot be directly dried. It needs to be boiled in water before drying. Boiling longan before drying mainly plays a bactericidal role, because the sugar in longan eyes is very high, and it is easy to breed bacteria and deteriorate under certain temperature conditions. If longan is not boiled directly, it will probably go bad before it is dried.
