1. Wear clothes "with a thick bottom and a thin top" and keep your legs and feet warm so that you won't feel cold.
2. Seize the opportunity. The climate in spring is changeable. One or two days before the arrival of cold air, mothers should appropriately add clothes to their children. Just the right "martial arts".
3. "Three warms and two cools". Three warms refers to warm back, warm belly and warm feet, and two cools refers to cool head and chest.
4. Allergic children should not "squat".
