On Facebook, Hang Du Cac posted an article related to the bird's nest product she advertised for on a livestream to sell.
The female TikToker said that she went to Nha Trang to clarify the product production process and had a meeting with representatives of the Vietnam bird's nest Association.
In a post on the website of the Vietnam bird's nest Association, Hang Du Cac shared: "During the livestream, I asked the crew to help me convert the 300mg protein content from the bird's nest. The crew informed me to convert it to 30g of the A5 bird's nest for production, so I did not respond in time and followed it, leading to confusion when informing about the product."
Hang Du Muc apologizes to customers and those working in the bird's nest industry, and commits to drawing experience, improving information control processes in communication, improving service quality...
It is known that the livestream session featured products that were advertised incorrectly at the end of 2024, in which Hang Du Cac introduced a bird's nest product and claimed to be made from whole bird's nest, a 70ml bowl with up to 30g of fresh bird's nest.
She also said that this product is a good quality A5 bird's nest, not scrap, but the price is only 188,000 VND/bowl. Hang Du Cac's statement attracted many controversial opinions
Many people believe that TikToker has advertised arbitrarily, exaggerated the quality of products, and lacked knowledge about products to bring to consumers.

Previously, on February 24, TikToker Quang Linh Vlogs also apologized for advertising confusingly about the product's uses that "a candy is equivalent to a plate of vegetables". He apologized for conveying inaccurate information, causing misunderstanding to customers.
Since the end of 2024, Quang Linh Vlogs and Hang Duoc, along with a number of others, have contributed capital to establish the company. 2 TikToker created many livestream sessions attracting hundreds of thousands of viewers, closing thousands of orders. There are even items that have just been live for a few minutes and are out of stock.
Thanks to the strong attraction on online sales platforms, Hang Du Cac and Quang Linh Vlogs have created many record-breaking sales sessions. The two gradually became closer and called each other "brother" and "brother".

The fact that celebrities and TikTokers have influence to participate in advertising but the advertising is incorrect, the advertising is exaggerated, and the function of the product is always criticized and opposed by public opinion.
