Simply preparing some food and drinks is usually a modest and polite way for the host to invite guests.
Source: Su Shi's "The Second Rhyme of Zhou Kaizu" in the Northern Song Dynasty: "From now on, when I go to Zhou Song, I will know that you laugh at Du You."
From now on, I will set foot on the road of Qingzhou Opera again. I will simply prepare some food and drinks to send Du You on the road.
"Thin wine" is a modest expression.
"Thin wine" is often a courtesy, just like saying "Yi". It is worth noting that saying "thin wine" is for people who have wine to drink, which is self-modesty. People who drink with wine must not say that this is "thin wine", otherwise it will make a joke.
There is also a saying that it is to prepare thin wine or thin drink. Now it is common in wedding invitations, indicating that the host's family is modest, saying that the prepared tables and drinks are not very rich, but snacks or drinks.
Similar to thin wine, it is "light wine". There is a saying in Li Qingzhao's ci that "three cups and two glasses of wine are not as late as he is". Although he drank several glasses of light wine, he couldn't resist the cold of autumn wind in the evening. There is no need for modesty here, so "light wine" can truly reflect the point of "low degree"
