Yuzi passed on the commander-in-chief of Xihe Instrument, you, and the commander-in-chief of Dingjun Mansion, Maoling, all of whom were passed on as adopted sons. I help regular teachers, son. It will be effective if you learn from the horse's bones and act according to the test. I foolishly thought that hearsay was not as good as seeing it with my own eyes, and seeing it immediately was not as good as seeing it.

The horse is three feet four inches high and four feet five inches around. The emperor issued a letter and ordered the horse to be placed in his royal highness Xuande with the name of a famous horse.
