Should pity fangs, print hair and buckle Chai Fei for a long time to express the poet's feelings.

"You should pity the dog's teeth and seal the moss, and Chai Fei will not open for a long time", explaining that the author has not met relatives and friends, and the garden door is closed, so he can't watch the spring flowers in the garden. However, it is very humorous, saying that it is probably because the garden owner cherishes the moss in the garden and is afraid that my fangs will leave traces of trampling on it, so Chai Fei has been delayed. The host is not at home, deliberately saying that the host intends to refuse the guests. This is to pave the way for the following poem. It expresses the understanding character of the author and poet and his feelings of cherishing spring.
