The kaiser coalition introduced the priority provincial professional team: the fujian badminton team. This was followed by the sponsorship of a number of provincial badminton teams representing the country's high level, including the xiamen, hunan, liaoning, beijing and aoshima. In 1998, kae-sung began sponsoring china’s young badminton team, and in 2000 ka-sung officially sponsored china’s young badminton team. In the same year, china’s young young badminton team used ka-sung’s equipment to participate in the 5th world young badminton championship. The kaiser brand is therefore of great interest in the international badminton community. In 2005, kaiser and the chinese youth badminton team succeeded in renewing their contract, marking the continued development of additional reserves by the kaiser brand with its technical strength. On 6 july 2009, the kaiser brand was officially incorporated under the umbrella of china's priority sports brand, li ning group, and became a member of the li ning group's multiple brands, marking a new stage in the development of the kaiser brand。
