It is ok to wear short-sleeved clothes for children in hot weather, but pay attention to the indoor temperature. Air conditioners or fans should not be blown directly at children to avoid catching a cold.
It's not too cold during the day in May. It is recommended to wear cool and breathable clothes, such as shirts, thin long skirts and thin T-shirts made of cotton and linen. If it is still cold at night or in some areas, it is recommended to wear warm clothes such as suits, jackets, windbreakers, casual clothes, jackets, suits and thin sweaters.
