Xue Lingzhi was the left scholar (a teacher who taught the crown prince). He wrote a poem to himself: 'The morning sun is round, shining on the teacher's plate. What's on the plate? Alfalfa has long rails. The rice is bitter and hard to spoon, while the soup is thin and easy to use with chopsticks. With this in mind, how can we keep warm in winter?' When the emperor visited the Eastern Palace, he wrote next to the poem, 'If you dislike the coldness of pine and cypress, go for the warmth of mulberry and elm'. The emperor was afraid to return..."
