In China, the first two total solar eclipses can only be seen in remote areas. One time was in 1980, which was only visible in Ruili, Yunnan, on the border between China and Myanmar, and the other time was after the Spring Festival in 1997, which was visible in Mohe, the northernmost part of China, on the border between China and Russia.

At that time, it was still winter there. During the day, the temperature is about MINUS 25 degrees Celsius, and at night it can reach MINUS 40 degrees Celsius, dripping into ice, and people can't even find water to wash their faces and gargle.

The total solar eclipse that arrived on July 22nd, 2009 is a good "secret" for China to observe the total solar eclipse once every 500 years, which makes domestic astronomers sigh. This is the most spectacular total solar eclipse in this century. It is rare that the solar eclipse has a wide area, a long time and a large population.

However, a total solar eclipse occurred on August 1 day in 2008, but only a few remote areas in northwest China were suitable for observation. As we all know, the eclipse is because the moon blocks the sunlight.

When a solar eclipse occurs, the area covered by the moon forms a shadow "cone" between the moon and the earth, and the total solar eclipse can only be seen when the surface of the earth rubs it.
