Hello, would you like to ask what the predecessor of Rishico is? The predecessor of Rishikang was Zhenshikang. Zhenshikang is an eye drop for the treatment of myopia, developed and produced by Tianjin Zhenming Biopharmaceutical Co., Ltd. (referred to as Zhenming Biopharmaceutical). In order to enhance the brand image, the brand name of the drug was changed to "Rishiba". The brand name is an important part of the brand image. The choice of brand name is related to the brand's competitiveness, influence and popularity. Therefore, Zhen Shikang's change of trademark name will help enhance the brand image and brand awareness, and attract more consumers' attention and choices. The change of Zhenshikang's brand name can better enhance the brand image, consolidate the brand position, and convey the company's development strategy to the market.
