As the theme song of the movie "Happy Face", the arrangement of "Olive Tree" follows the classical strings commonly used in Li Taixiang, with guitar as the main means of playing, supplemented by wind instruments, flutes and percussion instruments, creating a faint feeling of homesickness and sadness, which permeates people's hearts in the unique sound quality of Chyi Yu.

Li Taixiang commented on The Olive Tree;

The "Olive Tree" can well represent my life and thoughts at that time. On the surface, it looks like green mountains and green waters and dreams, but it represents my aesthetic view when I was young-"beauty" is a beautiful thing. In addition, there are some melancholy feelings. At that time, I couldn't write very heavily, but fortunately it was the same. "Olive tree" represents a dream. In this respect, the writing at that time was quite appropriate. If it is now, it may be painted with many brushes, but it will lose its simplicity and beauty. At that time, in addition to expressing their dreams, there was a trace of yearning for the other side who wanted to pursue the distance. "

San Mao commented on The Olive Tree;

"My friend Mr. Li Taixiang asked me to write some lyrics, and he urged me to write them down. I wrote nine songs in one night, one of which was Olive Tree. Because I like olive trees very much. Olive trees are beautiful. My husband Jose's hometown is in southern Spain, and the most famous is olive production. However, the song "Olive Tree" I wrote at that time sold for 500 yuan. Today, I spent more money on buying tapes for my friends than I got. I won't say how much money I made today. I didn't write two lines about this song, because this song was originally sold to Green, and later transferred to Brother Xin, so there are some copyright issues. I can't sing this song. There seems to be something like "Wandering is for birds and grasslands flying in the sky". I want to make a statement, because the "olive tree" is different from what I wrote at the beginning. If wandering is just to see birds and grasslands flying in the sky, there is no need to wander. "
