Today, many trademarks of Jinmailang have attracted attention. Jinmailang's trademarks such as "handmade," "premium," and "burst" are suspected of being misleading.

According to media reports, recently, Jinmailang sparked controversy with the word "handmade" on its noodle products. In a public response, Jinmailang stated that "handmade" is not a description of the production process, but a registered trademark, and they have stopped production of all products with the "handmade" trademark since the early hours of April 2. Public records of intellectual property information show that Jinmailang Food Co., Ltd. was established in August 2011, with Fan Xianguo as the legal representative and a registered capital of 1.23 billion RMB. The company has more than 999 trademark information, including trademarks such as "top grade," "Jinmailang Golden Egg," "Walnut Duo," and "Explosive," many of which are related to food products.
