As Guangxi, I still remember. I went to primary school in the 1980s. In some seasons, when the sun goes down in the evening and the black stars haven't come out, I will see several big stars in the sky, which are balloons. I often pick up some leaflets, and sometimes I see them floating down from the sky and running to pick them up. Once, a balloon should have fallen directly without exploding in the sky. I got up in the morning and saw someone rummaging in the field. My dad also went to find a pack of beef jerky. We children are sure to join in the fun. We found many leaflets, which may be as many as dozens or even hundreds of kilograms. Every child picked up a lot and went home. Later, people from the police station came to collect a lot, but of course not all of them. My favorite book is Eight Years of Anti-Japanese War.
