This is a song from the early 1980s, sung by Li Guyi. Song Lihua from the All-China Federation of Trade Unions also sang. Looks like Su Hong sang, too. Wang Jieshi Sherris seems to have sung, too. This song has a strong sense of rhythm, catchy melody and deep impression.
The lyrics are probably:
I will come again, I will come again, how can I forget all this?
I will come again, I will come again, how can I forget all this?
People here treat each other sincerely, even the air is full of love.
Friend, ah friend, let me say goodbye.
I will come again, I will come again, I will come again.
(repeat)
