In the heat of Japan's summer, we give greetings like "shochu omimai moushiagemasu" (暑中お見舞い申し上げます) during the heat, and "zansho omimai moushiagemasu" (残暑お見舞い申し上げます) when it lingers in late summer, like now. The summer has been so hot that apparently even the bugs can't fly as usual. Take care out there! 🍧
Yanquan, maybe you can find a Japanese article about the fact that even insects cannot fly.
