The store is jointly owned by Chenggong International and a local company in Hong Kong, and operates five young girls brands under Chenggong International. The store's positioning is high-end and focuses on design details. In addition, the company's clothing, each production volume is small, inventory is very small, and launch new every week, using fresh sense to attract customers.

The person in charge of the store stated that Hong Kong consumers are more likely to accept new things, and many women have experienced the girlhood era. Wearing adult clothes and children's clothing at this stage is not appropriate. The middle and high-end costumes with a touch of romanticism are just short of the girls' clothing market. Therefore, the store's development prospects are very optimistic.

Cheng Gong International was established in Japan in 1989. The first teenage fashion brand is Angel Blue, which has always been operated as a counter or in-store. Recently, several flagship stores have been established in Tokyo and other businesses have been developed horizontally. The company began to develop overseas business early this year. The first overseas branch was located in South Korea. Hong Kong’s Rainbow City Store is its second overseas branch.
