Before it is drunk, a libation must be offered by dipping the index finger in the liquid and flicking it towards the sky or earth as a toast to the ancestral spirits, and as an expression of the sentiment that when you have good wine you should not forget to share it with your predecessors. It is all part of the ritual.
在飲酒前都要舉行「灌祭」，就是以食指沾酒灑向天空或地上，向祖靈敬酒，表示有好酒也不忘與祖先同享，這是屬於儀式的一部分。
