After collaborating with actor Daniel Wu to promote coffee products in late June, Guming Tea recently rolled out packaging bags featuring his image at stores nationwide, which unexpectedly sparked widespread dissatisfaction among consumers. Many customers complained on social media that the bag design was "not aesthetically pleasing" and that the celebrity's portrait was too large, saying carrying it felt like "health supplements for middle-aged and elderly people" or "soaking goji berries," and some even said they wanted to throw it away as soon as they received it. Some netizens argued that although Daniel Wu has high national recognition, he is no longer young and does not fit the positioning of a youthful tea beverage brand; others pointed out that the brand should consider scenarios for secondary use of the packaging.

Staff responded that filtering the fruit puree was not required during preparation, and the final product varies due to differences in technique. Interestingly, netizens are divided on the issue—some suggest adding a filtration step, while others believe the fruit residue is precisely proof of "genuine ingredients." Behind this controversy lies the challenge of balancing taste and health in fruit-and-vegetable teas. [more…]
