When I miss you is written by Jin and sung by Wu Dashuang.
The lyrics of this song are like this: When I miss you, my heart is moved. Your elegance is the most perfect, I can't say enough. I will never forget your great rescue with ten precious blood. It was a pair of wonderful hands that healed me. Tears of gratitude flow when I miss you, and the joy of satisfaction is hidden in my heart. When I miss you, even though the mountain is high and the road is far away.
