Xiao Ming is learning calligraphy, but he doesn’t want to practice. His father said: "("Good work comes from hard work, but waste comes from play.)

Xiao Ming always likes to do some disgraceful things. I told him several times, but he didn't take it seriously: "I didn't do anything illegal, so why should I be afraid of such a small thing?" The teacher said to him: "(Don't do evil because it's small, don't do good because it's small)".

Hope it will be adopted as a standard.
