Li Ruji has always had a face as cold as ice. Even when he was wearing a purple robe and a purple belt and was a highly respected minister, he still looked like he would not approach strangers. Xiao Mu often scolded him behind his back. At first, he tried every means to make him laugh. Some villagers in Gyeonggi Province caught a white deer. Xiao Mu built a yard to raise it. He was so excited that he held a flower banquet and invited the ministers to drink by the water. In fact, he wanted Li Ruji to see his deer. Li Ruji looked at it and said: "The white deer is an auspicious beast. The ancients said that the white deer will appear and the world will be peaceful. However, every brick, tile, grass and tree in the White Deer Garden of the Holy One is all about the hardships of the people. I wonder if the white deer knows it."
Li Ruji had never smiled before, and Xiao Mu only wanted to make him cry.
