Garbage covered with golden jade coat ―― shiny appearance and rotten inside; Beautiful appearance, evil heart; superficially clever
Nothing ventured, nothing gained-nothing ventured, nothing gained; If you want to find pearls, you must dive underwater.
The edge of the sword comes from sharpening, and the fragrance of plum blossoms comes from bitter cold.
Even the smartest person will make mistakes in his 1000 plans; Even a wise man worries a lot, and there will be a loss; Even the wise are not immune from making mistakes.

Don't do evil, no matter how small it is; Don't forget to do good, no matter how insignificant it is.
