In the national industrial and commercial credit information inquiry system, the enterprise "Guangdong Tainiu Vitamin Beverage Co., Ltd." cannot be found. Even if the search scope is expanded by "Guangdong Tainiu" and "Tainiu", it is still impossible to find companies with similar names. Then it is most likely a non-existent enterprise or a virtual company name. In the national trademark inquiry network, searching for the "Wangzai" graphic and word mark, I can't find any applicant company with the name similar to that of Tainiu and Guangdong Tainiu, that is to say, the trademark is likely to be infringed.
