"Nan Nan, it's a good habit of yours to drink plain water. Nowadays, there are all types of fruit juices and coke, but they are not healthy for the body. Plain water is the best." Old Master Zhai either drank plain water, tea, or wine. He would not drink other drinks.
"Grandpa, I have the same sentiments. The fruit juices are not a hundred percent pure juices. They are not as good as those that we blend by ourselves. As for coke and soda, they have high sugar content. It is not healthy for the body." In the previous life, Qiao Nan was too poor to have these drinks. She remembered that these drinks were unhealthy. Hence, she did not have them in this life.
