(find someone to teach, say "teach"; Please correct me when I said "Yazheng"
Give away the work and say "the axe is right"; The other party wrote to say "Shu Hui")
For example: "Mr. Wu corrected his mistake."
Inscribe a word (poem) a book (with a seal)
For example: "Li Baiwang Lushan Waterfall Poem Half a Xiao Ming Book (Zhang) (the standard is an empty chapter) (Xiao Ming Book)"
