Why did Lin Chong, the head of Linfeng Snow Mountain Temple, let the store recognize the wine gourd first?

Because the store recognized the wine gourd of the old army, Lin Chong was allowed to eat meat and drink in the electricity. If the store doesn't recognize the wine gourd, Lin Chong may return to the thatched cottage before it collapses, and won't spend the night in the mountain temple. In this way, Lin Chong may be crushed to death by the thatched cottage and burned to death by Lu and others, and the story will not continue to develop.
