What are the six-character quatrains that thank or praise the teacher?

First of all, I want to explain that there is no such thing as a six-character quatrain, only a five-character quatrain or a seven-character quatrain. Please refer to: \x0d\ four degrees of spring breeze, \ x0d \ x0d \ several times of autumn rain cleaning. \ x0d \ x0d \ black hair and frost weave the sun and the moon, \ x0d \ x0d \ chalk has no words to write the spring and autumn.
