In the 19th year of the Republic of China, he began to work as a music teacher in "Zhixing Qinxing" in Guangzhou. As an amateur, he participated in radio performances, and the music program was based on the meaning of "Heaven gets one to be right, the earth gets one to be peaceful, people get one to be spiritual, and things get one to be fine", so he changed his stage name to Liu Tianyi. In the 20th year of the Republic of China, he participated in the famous amateur music club "Su Club" in Guangzhou as a gaohu player.

The rain hits the bananas, etc. Liu Tianyi created a combination of gaohu (folk musical instrument) and piano (western musical instrument), which is innovative and popular with audiences. During this period, his gaohu skills became more and more mature, and gradually formed his own style, which has reached the level of professional musicians.

In the 24th year of the Republic of China (1935), Liu Tianyi went to Japan to study music theory at the Oriental School, and returned to China in the 27th year of the Republic of China. Soon, Guangzhou fell, and the family moved to Macau. To make a living, he worked as a clerk in a hotel. After 10 years of turbulent and turbulent life, he was unable to engage in normal musical activities. In the 35th year of the Republic of China, he participated in the establishment of Jinyu Club, and often performed in Guangzhou, Hong Kong and Macao with Lu Wencheng, Yin Zizhong and other Guangdong musicians. At the end of the 1935, he moved to Hong Kong. At that time, very few people in Hong Kong could play the guzheng. Liu Tianyi began to play the guzheng immediately. In 1950, he played the guzheng and dubbed the feature films "Home", "Spring", "Autumn" and "Peerless Beauty". He also recorded Guangdong famous songs with Guzheng solo "Night Rain at Banana Window" and "Song on the Plug", Guzheng Dongxiao Ensemble "Flowing Water and Clouds", Guzheng and Yehu Ensemble "Birds Shocked" and so on.

In 1954, he returned to Guangzhou, where he worked in the Guangdong Music Research Group, as a gaohu lead player and a guzheng soloist. In 1955, with the music group of the South China Song and Dance Ensemble, he went to Lushun Dalian to perform to express his condolences to the Soviet Red Army.

Liu Tianyi devoted himself to the study of music, deliberately innovated, and established his own unique playing style. Before 1930, his gaohu repertoire "Birds Throwing in the Forest" used "koudouzi" to imitate the sound of birds. Liu Tianyi felt dissatisfied and wanted to achieve "no one has what I have, but one has my essence". He canceled the koudouzi as the bird's sound, and used the high-pitched area of the gaohu, using the method of citing priorities, combined with the appropriate glissando to make bird calls, the effect is more realistic. In order to make the sound of birds more euphemistic and moving, I go to the woods, parks or places for buying and selling birds in the suburbs every morning to listen to the songs of birds, and finally changed "Birds to the Forest" into a Gaohu solo.

The first Gaohu solo he played was "Spring to the Field" by Lin Yun. In order to express the idyllic beauty, he absorbed the playing skills of the violin and expanded the common range of traditional gaohu performances, from three or four positions to five or six positions, and created a cadenza with three consecutive octaves. The above performance methods such as big jumping and broken bow sliding have creatively improved Gaohu's skills, making the emotional expression of the music light, smooth, free and beautiful, and welcomed by the audience. This is the first Gaohu solo in the history of Guangdong music. At the beginning of 1957, Liu Tianyi composed and performed "Fish Swimming in Spring Water". He used the method of playing septuplets and octatuplets fast arpeggios with one bow, and created a transparent and clear natural original sound in the second position of the gaohu. In order to improve this original sound, he spent half a year to bring his gaohu skills to a new level.

The music composed by Liu also includes the Gaohu Unio "Flower Market Welcomes Spring", the Gaohu Solo String "Reminiscence", and the Suo Na Lead Play "Fireworks". He is good at absorbing the strengths of others, gathering together, and forming a family of his own.
