The Light of Friendship Lyrics:

How many confidants do you have in this world?

How many friendships can last forever?

Today, I left you to shake hands with you.

Friendship is always in our hearts.

There is a farewell today.

We will definitely get together in the future.

Even if we can't meet.

Be friends forever

Said there was Mount Wan Li.

Two places apart.

No need to meet.

I know in my heart.

Friendship cannot be changed.
