According to legend, in the early years of the Republic of China, a restaurant in Chongqing hung a bottle of French three-star brandy brandy on the door, soliciting couplets. There were many people who responded, but the boss was always dissatisfied. Guo Moruo was still very young at that time. He rushed there after hearing the news. He thought of a famous dish in Sichuan that could be related to wine, so he mentioned:

Three-Star Brandy,

May Huang Meitian.

Generally, people only know that "Huang Meitian" refers to the climate but not the name of the dish. They mistakenly think that this couplet means "the ruthless pair". In fact, one wine and one dish have very coherent meanings. The brand name and wine name are embedded in the upper line, and the time and dish name are embedded in the lower line.
