"Little Luo Xiaoxiao, still wetting the bed? The teacher has prepared some Silkworm Chrysalis for you. When you get home, have your parents roast a few for you to eat. Once you eat these, you won't wet the bed anymore..."

"Little Dou Dou, don't eat too much fruit, especially watermelon. It's fine in summer, but you shouldn't eat it in winter. Always remember to eat fruits in season; off-season fruits aren't good for your health..."
...
"Little Jiang Zeshen, don't cry secretly under the covers at night. Being overly sad and worried will harm your Fei Jin, which is why you're always coughing. If you have anything on your mind, speak to your grandparents, or you can talk to the teacher, but don't keep it bottled up..."
...
Each of Lu Jiu's letters was opened, and over fifty families read what he wrote.
This left many parents quite astonished.
