The most beautiful starry sky I have ever seen is a hot spring in Conch Trench. It describes the star as a diamond hanging on black velvet. What MAUNA KEA SUMMIT sees is the real starry sky full of stars. It feels that the night sky can't wear them. At night in Shanghai, only when the weather conditions are excellent can there be so many stars shining in the sky at night. Actually, the stars are always there, but they can't be seen in the night sky of Shanghai. The city's lights are too bright, leaving behind the beautiful stars.
