Watermelon Taro, a stationery, was discontinued because there were too many pirated copies of Watermelon Taro, which made the genuine manufacturer unprofitable and had to give it up. The competition in the stationery market is fierce, new brands and products are constantly emerging, and pirated products also change with the changes in market demand. These pirated products have brought great impact to genuine products, resulting in no profits or even losses for genuine manufacturers. In addition, due to the adjustment of brand management strategy, some well-known brands will also suspend the production of some products.
