Both companies are Taiwanese private companies, both engaged in food manufacturing and distribution. The difference is that Master Kong is listed in Hong Kong, while Uni-President is listed in Taiwan.

1. Master Kong is a Hong Kong listed company, and its two major shareholders, Ting Hsin (Cayman Island) Holdings Co., Ltd. and Sanyo Food Co., Ltd., hold 33.21 and 33.20 shares of the company respectively. The predecessor of Ting Hsin Group was Ding Hsin Oil Factory, which was founded in Changhua, Taiwan in 1958. In 1974, it was renamed Ting Hsin Oil Manufacturing Company and mainly produced castor oil for industrial use. In 1988, when mainland China implemented the reform and opening up policy, the Wei brothers saw the promising market in the mainland and decided to go to the mainland to investigate investment. In the early days of the group's business, it successively invested and set up factories in Beijing, Inner Mongolia, Jinan and other regions, and launched well-known products such as "Dinghao Fragrance Oil" and "Kanglai Egg Crispy Rolls". However, due to the low overall domestic consumption level at that time, these products were "well received but not popular", which once put the company's business investment in mainland China into trouble. It was not until the end of 1991 that the Wei brothers decided to invest in convenience foods. On July 18, 1992, Tianjin Dingyi International Food Co., Ltd. was officially put into operation, and "Master Kong" instant noodles were born.

2. Uni-President Enterprise was established in Yongkang, Tainan in August 1967. It was listed in 1987 and entered the mainland in 1990. Its degree of internationalization is higher than that of Master Kong, and the industries it involves are also more complex
