It feels very cold at 8℃ in Guangdong. Is it normal?

Under normal circumstances, houses in Guangdong are designed for heat dissipation, with thin walls and ventilation. It's colder inside than outside, and the air is humid. At 8 degrees Celsius, it will feel colder. Pay attention to cold and warmth, and don't take off your clothes at will, because the weather in Guangdong may be 30 degrees Celsius at noon and 10 degrees Celsius at night. If it rains, cycling on the road is prone to hypothermia and the like.
