The story begins with the setting of a girl named Ha's livestream work. She advertised for the Xuan Dam Milk Tea brand, as delicious as homemade. The young green rice milk tea is advertised to have the flavor of Hanoi's autumn, excellent quality and is directly "mukbang" by Ha.
While she was selling goods, her parents-in-law and son had persistent diarrhea and called for help, but Ha was busy working and could not handle it.
However, when she returned home, Ha herself also had vomiting and diarrhea. Mr. De - Ha's husband - diligently sought the cause of the poisoning for the whole family.
De believes that when going to eat at a restaurant, you need to have "belief" in the restaurants, because being crowded is delicious, being delicious means clean. He discovered that after drinking milk tea, eating mixed rice cakes and rice at a restaurant on the street, his whole family had digestive problems.

De went to the milk tea shop that his wife and children often drink and discovered that this shop was very unsanitary, using unsanitary hands to prepare drinks. The owner was shocked and said that customers had been drinking for many years but had no problems.
After that, De went to the mixed-use bakery and discovered the owner of the restaurant lifting food from the ground. She admits that "clean will be the only thing" but uses her hands to scratch her legs, move her nose and mix rice paper.
When trying dusty rice, De and her juniors found the kitchen to be damp, with mice, dirty and not ensuring food hygiene and safety.
However, all of these restaurants are advertised as delicious, cheap, and hygienic. They affirm that the food is fresh, cleanly processed, and of good quality.
To improve the health of her family, De decided to buy genuine milk online, with a 40% discount. At this time, his family received information from the authorities about a large-scale counterfeit powdered milk production ring that had consumed tens of thousands of products.
Because of drinking fake milk, De had to be hospitalized for emergency care. He said that he bought the product because he trusted the big brand and had prestige in the market.
" buying and selling online is not only because it is cheap, but people are also attracted to discount policies. They do not buy what they need, and feel sorry if they do not buy," Ha expressed his opinion on the current situation of consumers shopping online.
