The parent company headquarters of Xihu Brand is located in Hangzhou, Zhejiang Province. It originated from the Han Yongji Cattle Farm outside Wangjiangmen in 1897 and was awarded the title of "Zhejiang Traditional Time-honored Brand". Through decades of operation and development as well as mergers and acquisitions, the company has now become a comprehensive dairy group integrating "grass, livestock and dairy" and covering "production, supply and sales".

This project is a milk product launched by West Lake brand with lutein ester as its selling point. The packaging color is green, which is widely found in green leafy vegetables. The layout symbol is a yellow leaf, making the keyword "leaf yellow" easily recognizable visually. At the same time, it amplifies the selling point information and reduces the cost of information transmission.
