First, you can let children know that carbonated drinks are really bad. No matter how old people are, carbonated drinks are very popular, especially those children who will clamor for their parents to buy a second time after drinking them once. No matter what parents say is harmful, these children are always disobedient and insist on buying. Some children don't listen to their parents because they don't know how harmful these carbonated drinks are to their health, so I personally think that setting such tips can let these children know clearly that their parents are not lying to them. I also hope that these children can drink less carbonated drinks before they are underage, which is helpful to their health.
Second, it can make everyone healthier. In fact, many young people know that carbonated drinks will have an impact on our health, but people still can't help but buy them. Because every time we buy, we become irrational. If we set such a reminder next to carbonated drinks, we will feel that it is not worthwhile to hurt our health for a bottle of drinks after reading it a little before buying, and we will buy other healthy drinks, so that our bodies will become healthier and healthier. Most people who work in Shenzhen are very busy every day, and they usually have little time to exercise, so such tips can make these people realize the importance of their health and improve their awareness of maintaining their health.
This may reduce the sales of carbonated drinks, but it can make everyone healthier. For those who really want to drink carbonated drinks, they will actually continue to buy them, so I think this hint is still necessary.
