Kang Jia holds a master's degree from Xi'an Jiaotong University and Shanghai Jiaotong University. In 2021, Kang Jia founded Belink, focusing on the middle-aged and elderly consumer market. The platform taps into the silver economy through gatherings, travel, social events, and other scenarios, addressing the product and service mismatch for middle-aged and elderly people. Kang Jia believes that China's silver economy will enter a period of explosive growth in 2023, and retired people aged 50-70, with their combined spending power and internet adaptability, are the core target user group.
