After returning to his native land in 1983, Professor Cai Jikun, who had been away from his motherland for more than 3 years, began to give lectures all over the country, and at the same time conducted performances in various places. He was successively hired as honorary visiting professor by Xiamen University, Huaqiao University, Fujian Normal University, Anhui Normal University and Jilin Art College, and honorary music director and chief guest conductor of the orchestra by changchun film studio Philharmonic Orchestra and Fujian Song and Dance Theatre. Professor Cai Jikun is deeply educated by Mr. Chen Jiageng's patriotism, and he is deeply concerned about the situation of the domestic music industry. He keenly observed that the music education in China is still very weak, and there is no formal music university except some colleges and universities with music departments that mainly train music teachers. He felt a heavy responsibility and came up with the idea of establishing a music university. He believes that it is a practical way to fully mobilize social forces at home and abroad to run schools, develop higher music colleges in the form of adult education, and achieve the goal of cultivating music professionals at different levels when there are certain difficulties in the re-investment of national team education at that time. Therefore, he is adhering to the ideal of developing social music education and further strengthening the cultivation of music talents, and has far-sightedly practiced a arduous pioneering road of establishing higher music institutions in Fujian Province.

Previously, Cai Jikun had founded two music colleges, namely Fujian Provincial Music College and China Music Education Institute. Fujian Provincial College was established in February 194, when Cai Jikun was ordered by General Chen Yi, the chairman of Fujian Provincial Government, to set up the school in Yong 'an, then the capital of Fujian Province, as the first president, and later changed its name to National Conservatory of Music, which was one of the three higher music institutions in the Kuomintang-controlled area during the Anti-Japanese War, and trained a large number of musical talents for the country. After liberation, the school merged into the East Branch of the Central Conservatory of Music, now the Shanghai Conservatory of Music. In 1942, when Cai Jikun was transferred to Chongqing to serve in the Ministry of Education, he and Gu Yuxiu (Yiqiao), then Minister of Government Affairs of the Ministry of Education, founded the China Conservatory of Music Education, which was an institution of higher learning specializing in training music professionals during the Anti-Japanese War. The students trained became music elites active in various fronts in War of Resistance against Japanese Aggression, and some even became influential composers, singers and conductors in the world.

In 1988, Cai Jikun, who had settled in Fuzhou, immediately devoted himself to the preparation of Fujian Social Conservatory of Music. After repeated consultations, he finally decided to jointly run Fujian Social Conservatory of Music with Fujian Normal University, Xiamen Art Education College and other institutions, and began to recruit students in the second half of 1988. But at this time, Fujian Social Conservatory of Music is only a transitional form, and there is no independent school building of its own. In order to improve the Conservatory of Music as soon as possible, regardless of his age, he ran around and personally surveyed the school site. After the approval of the provincial government, he finally settled in Shoushan Village, Cangshan, Fuzhou. In order to raise funds, on the one hand, he sold his villas, vehicles, precious paintings and calligraphy in the Philippines and returned to Fuzhou with eleven boxes of precious music scores, materials and all his savings; On the other hand, he went to the United States, Southeast Asia and other places to lobby and encourage overseas Chinese to donate money and materials to contribute to the music industry of the motherland. Many overseas Chinese gave their money to help each other under his inspiration.

In p>1993, the foundation stone of Fujian Social Conservatory of Music was laid in Shoushan Village, Cangshan, Fuzhou. At the beginning of 1994, after a year of intense construction, office buildings, teaching buildings, comprehensive buildings, dormitory buildings and piano buildings with donors' names carved on them sprang up, ending the history that there was no special conservatory in Fujian for nearly half a century. In 1994, the Fujian Provincial Government approved the establishment of Fujian Conservatory of Music, and Cai Jikun personally served as the chairman and dean of the college, and kept the name of "Fujian Social Conservatory of Music". In September, the college enrolled the first batch of more than 6 students, and opened three majors: vocal music (Bel Canto and folk singing), keyboard (piano, accordion) and orchestral music (including folk musical instruments), with famous musicians Lang Yuxiu, Zhu Yafen and Shao Zhongshi as the department heads respectively, and Cai Jikun personally took the teaching task of conducting classes, becoming the oldest and most qualified "full-time professor" in the hospital. The college adopts the method of "open school and closed teaching", with the motto of "Xiu De cultivates arts and strives for self-improvement" and the direction of "patriotism first, moral character second and specialty third", aiming at cultivating senior music talents with all-round development for the country.

in his octogenarian years, Mr. Cai Jikun's spirit of sparing no effort to destroy his family and promote his studies has aroused great concern of the state, the Ministry of Education and provincial leaders, and has also been unanimously affirmed by them. In November 23, in recognition of Mr Cai Jikun's outstanding contribution to music education and the establishment of a conservatory of music, Wang Yifu, then vice governor of Fujian Provincial People's Government, presented Mr Cai with a plaque and a certificate of "Educating Talents through Music".
