Explanation: Xiangde wrote this letter with great thoughts and chants. After staying in Hangzhou for two months, I have just come out of the customs. I have been intoxicated by watching the drama, which is a great event of spring. It is a joy to know that the subordinates of the magistrates and the princes and princes have the same affection. Tang Hou said: It is strange that Wang Bai won by You Run this year. The scenery is peaceful in early summer, and I wish you a long life. Xiang paused. Tongli was a farmer in his time. The big cake is extremely precious, and the green pot is slightly thick. I paid my greetings in a hurry before leaving, but I didn't pay enough attention to them.
