Ghost weather, cold, cold, dead, hot, hot, dead.

Just say: be careful of catching a cold.

Just give him such a reply. You said the ghost weather is very annoying now. The clothes I wore when I left in the morning were too thick. Warm people up at noon, and then take them off and freeze in the afternoon. What's the weather like now? Anyway, we really can't tell the weather in the northwest now. Cold and hot light is easy to catch a cold.
