It is the song "Thousands of Rivers and Mountains Have Been Traveled"

Lyrics:

I once held a heart in my hands

Wandering around in this world

I have stood up to the earth and also to the sky

There is still softness in my heart

The years have taken away my appearance

I can no longer see the young man I once was

Spring passes and autumn comes, the frost spreads

The enthusiasm remains unchanged

Thousands of rivers and mountains have been traveled

Taste the cold and warmth of the world

Love is as gorgeous as fireworks

I have loved and hated without regrets

Thousands of rivers and mountains have been traveled

Why fear that the sea will turn into a mulberry field

Life is short after the glitz

Cherish every day

Time has taken away your appearance

I can’t see the boy I once was

Spring passes and autumn comes and frost spreads

My passion remains unchanged

Thousands of rivers and mountains have been traveled

Taste the cold and warmth of the world

Love is as gorgeous as fireworks

I have loved and hated but never said regret

Thousands of rivers and mountains have been traveled

Why fear that the sea will turn into a mulberry field

After the glitz, life is short

Cherish every day

After the glitz, life is short

Cherish every day
