On July 22nd, 29, the total solar eclipse will occur around 9: a.m., and the total solar eclipse belt will sweep across the following major cities from west to east. People living in these areas will have the opportunity to see the once-in-a-century total solar eclipse for a long time, which lasts for 4-5 minutes. For the total solar eclipse, it is a long night. Kangding, Ya 'an, Leshan, Chengdu, Zigong, Neijiang, Suining, Nanchong, Chongqing, Dazhou, Qianjiang, Yichang, Jingmen, Jingzhou, Jiangling, Shashi, Kaogan, Xianning, Wuhan, Huanggang, Ezhou, Huangshi, Lu 'an, Hefei, Anqing, Chizhou, Chaohu, Wuhu, Tongling, Huangshan and Xuanzhou. This is almost the whole Yangtze River basin can see the total solar eclipse, about 4 million people will see it. After carefully checking the above areas, I found that Huangshan, the place I always wanted to travel, is near the center of the total solar eclipse. Great, kill two birds with one stone. Of course, the Hangzhou Bay Bridge in Hangzhou, where the center of the total solar eclipse passes by, is also a very good choice to watch the total solar eclipse at sea on this nearly 5-kilometer-long sea-crossing bridge. The conditions for a total solar eclipse are that the three celestial bodies, the sun, the moon and the earth, should be just impartial or very close to a straight line. This kind of opportunity can only be seen once every three or four hundred years for the same observation point, and the longest time when the sun is completely covered will not exceed 7 minutes and 41 seconds. When observing the total solar eclipse, you must use special or self-made equipment. It is strictly forbidden to observe the sun directly with the naked eye to avoid damage to your eyes.

As long as human eyes look directly at the sun for a few seconds, it may cause permanent damage and even blindness. If you observe the sun through a telescope without proper dimming equipment, the consequences will be even more unimaginable.
partial solar eclipse and annular solar eclipse can't be watched without taking special safety measures. In the partial eclipse stage of the total solar eclipse, even if the surface of the sun is covered by the moon for 99%, the photosphere formed by the new moon will still be harmful to the eyes. Don't try to observe the sun in any partial eclipse, annular eclipse or partial eclipse with naked eyes.
Here are some scientific methods for observing the total solar eclipse:
Ink observation method
You can take a basin of clean water, add ink, and see the sun in the total solar eclipse through the reflection of the water.
Pinhole projection method
Two boards are used, and a small hole is dug in one board, so that sunlight can pass through the small hole and project onto the other board, and the shadow of the partial eclipse of the total solar eclipse falls on the clapper.
Telescope projection
It is similar to pinhole imaging, but don't shake your hands, or the shadow of the sun will run back and forth. And never look at the sun directly with a telescope. If you look at the sun directly with a telescope, you must use a filter.
