According to the Sanwen Trademark Design Registration Website, the origin of the Wahaha trademark is closely related to a school-run enterprise. In 1987, Zong Qinghou contracted the distribution department of this school-run enterprise and began to develop his own products. In order to find a suitable name for the oral liquid for children, Zong Qinghou decided to publish a prize-winning name notice in the Hangzhou Daily. Among many submissions, the name "Wahaha" was chosen because it is particularly suitable for children's products and has a sense of joy. In addition, the pronunciation of this name is easy to imitate, loud and harmonious, easy to remember and accept, and it is connected with the widely circulated children's song "Wahaha", further increasing its popularity. Therefore, the "Wahaha" trademark was born and gradually became one of the important brands in China's beverage industry as the products became popular.
