What is the square dance with the lyrics "two together"?

Two Together

Sung by:Zhang Di

The evening wind rises and the setting sun is low and the willows are swaying

Wandering on the willow embankment in the shade of the flower garden

Who is two together

The sky is clear and the swallows fly south

Throughout the western side of the painting building

Already I know that there is no good news

The two are two together

Two Together

Two together

Two together

Two together

The two are two together

Only in my sleep

---Music----

The evening wind and the setting sun are low, and the willows are swaying

Wandering in the flowery willow embankment

Who is there who is attached to each other

The sky is clear, and the swallows are flying south

Through the west side of the building

We know that we have no news

We won't be able to send any good news

There is a lot of news in this world, but we have no idea what we have been doing.
