If you do one thing, you will be meticulous.
-Shi Yang "Shicheng Cui Yanlun learning articles" cited Cheng Yi.
As long as one thing is casual, there is no carelessness.
Shi Yang was a Neo-Confucianist in the Northern Song Dynasty. The idiom "It snows in front of Teacher Cheng Yi's house" comes from Shi Yang. When the teacher woke up from a nap, "the snow was a foot deep outside the door", which became the most famous story in history about respecting teachers and stressing morality. The Collection of Speech by Cheng is a collection of speeches by Cheng Yi and Cheng Hao. These two sentences remind people that if you are afraid in this world, what you are afraid of is seriousness. Being serious means being meticulous in everything.
