In the third part of Princess Zhu Huan, Erkang is dead. What's the name of the song that Wei Zi sang on the piano?

Heaven and earth will meet. Lyrics: Qiong Yao Composed: Xiao Jian Singing: Liu Pan recalled how much tenderness was deeply rooted in the mountains and how many past events were sent far away. It has become an endless pain in my heart. Since I left you, the porcelain mandarin ducks on the roof have become dense with morning frost. It's been a long night. Who said goodbye to * * * reminds us that heaven and earth will meet eventually. Why doesn't the vast soul sleep? When will the beauty in the depths of the ocean be dreamt again? Smile very gently, very gently. We have met in a trance. Dreams come and go. It's a miracle. It should be unobstructed. In the old days, the Moss Mountain Alliance is still wandering alone. I have an appointment to wait for a few calls.
