#PI No matter how high the sky is, one can always reach the clouds.

No matter how treacherous the road is, persistence will surely flatten the obstacles.
Don't wait for the wind to come, raise the sail yourself.
Do not fear the dark night, hold tightly to the source of fire,
Those who have light in their hearts will always walk in spring.
To do anything, one must have fearless courage, take the initiative to create opportunities, and master the direction; as long as one has hope, life will always be full of vitality.
