After the two children discussed it, they didn't go out to play the next day. Instead, they wrote a letter to Qi Xiuyuan. The two of them wrote a few words each and told Qi Xiuyuan that they had voluntarily switched their seniority. They urged him to listen to the opinions of the parties involved and not be stubborn. Otherwise, they would be unhappy.
The two children used Little Bear's messenger pigeon to send the letter. In less than a day, it arrived at the palace.
When Little Treasure retrieved the letter and saw that it was for his father, he looked at it in surprise. Seeing that the handwriting on it was neither Little Bear's nor Fourth Uncle's, and the tender handwriting, it was obvious that it was written by a child. Feeling half puzzled and half curious, he took the letter to look for his father.
