The edge of the sword comes from sharpening, and the fragrance of plum blossoms comes from bitter cold.
A lazy youth, a lousy age.
Perseverance, the stone can be carved.
Friendship is the light of our life.
Only mothers are good in the world, and children with mothers are like babies.
Intimidation and death are the direction of the complaint.
Singing without soul decoration can't bury the direction where you lie down.
A bird with broken wings will never forget the direction of flight.
Even a dead bird will choose the direction of flight.
