The Starry Sky Belongs to Children

The Starry Sky Belongs to Children
During the winter vacation, when I went to Nanbei Lake with my relatives (a dozen or so people), I casually mentioned whether you could see a few more stars here at Nanbei Lake than in Shanghai. At first, Mom, Dad, uncles, and aunts all seemed completely at sea, until I added that nowadays in Shanghai you can hardly see even a few stars at night; then the “adults” were all astonished— in their impression, the night sky still looked full of stars, so many that they were beyond counting.

Remembering the Observatorium of Gezhi Middle School
For a long time I have always said that I had never truly gazed up at the brilliant starry sky—but then I suddenly remembered something: it turns out that, although it was only simulated, I really had once gazed upon a brilliant starry sky! I remember it was in fourth grade of primary school. At the time, I was in a cross-grade division of the Singapore Primary School Mathematics Olympiad and won third prize, which gave me the chance to visit Gezhi Middle School.
