The reason why Liu Yilong, Emperor Wen of the Southern Dynasties, was selected: He loved to eat citrus. Emperor Wen of the Song Dynasty was seriously ill, so he asked his younger brother Liu Yikang to be the acting emperor.

Therefore, those who give gifts should divide the gifts into two, give the top quality to Liu Yikang, and leave the inferior quality to Emperor Wen.

Emperor Wen once ate an orange and found that it was small and astringent.

After Liu Yikang saw it, he brought Emperor Wen some big and sweet ones from home.

Reason for selection of Song Taizu Zhao Kuangyin: Zhao Kuangyin got up suddenly in the middle of the night because he loved to eat sheep liver.

At this time, he really wanted to eat sheep liver, but he was hesitant and refused to order.

The servants on the left and right looked confused and said, "If you have anything to do, just ask us, and we will definitely do it!" Then, Zhao Kuangyin's witty answer once again showed his unique cuteness.
