On April 29, 2016, Hangzhou Zhinai Sanitary Ware Co., Ltd. was founded, and the "WLJBIDET" brand was officially launched. As one of the first brands in China to master the core technologies of intelligent sanitary ware, the key task during this period was to lay a solid technological foundation, focusing on the research, development and design of core products such as intelligent toilets and intelligent toilet covers. By virtue of its independent control over core technologies, the brand formed a differentiated competitive advantage in the early stage of its establishment, built a solid technological barrier for subsequent market expansion, and achieved a crucial breakthrough from scratch.

Entering this stage, "WLJBIDET" accelerated the construction of full industrial chain capabilities. On the R&D front, it set up high-tech intelligent R&D centers in Hangzhou and Shanghai to strengthen technological innovation and product iteration; on the production front, it built a large-scale production base in Zhejiang and established a full-process management system covering product design, raw material procurement, production and manufacturing, sales and after-sales service. At the same time, it strictly implemented certification standards such as ISO9001:2008, EU CE and national CQC. The product quality was widely recognized by the market, and the brand image of "high quality" gradually became deeply rooted in the hearts of the people. The number of after-sales marketing outlets across the country grew steadily, laying a solid foundation for large-scale development.

With the comprehensive maturity of the R&D and production systems, "WLJBIDET" has entered a period of brand leap. The number of after-sales marketing outlets nationwide has exceeded 1,200, and the market penetration has continued to increase. Its products have successfully entered many high-end places such as Shanghai JW Marriott Super Five-Star Hotel, Jinmao Tower, and Guangzhou China Hotel, and the application scenarios have expanded to multiple fields such as high-end residences, Grade A office buildings, hospitals, and government buildings. With its excellent product quality and comfortable and convenient user experience, the brand has become an important symbol for consumers to pursue a perfect home life, firmly ranking among the top echelons of the domestic sanitary ware industry in terms of strength, and establishing an industry benchmark image.
