British poet Sidney
The pleasure of doing good is the only reliable happiness in life.
Russian writer lev tolstoy sent charcoal in the snow,
Turn a blind eye to the cold in December.
Add China's hair between the green hairs,
The three-foot platform swayed with laughter.
How much blood and sweat,
Go down in history without seeking fame.
To provide convenience for a friend is to do good for yourself.
Dutch philosopher Erasmus
