According to China's tomb geomantic omen, both the graves of ordinary people and the Ninth Five-Year Supreme Mausoleum should be green mountains and green waters. Only in this way can future generations be blessed and prosperous. However, Cixi decided not to. She wants to do something new. People are green and full of vitality, and she comes. Nothing grows and birds don't shit. Her personality requirements are unprecedented, and she has no experience to learn from. At that time, she was worried about the builder of the mausoleum.
In order to solve this wonderful problem, grave robbers read extensively and visited all over the country, and finally found some barren graves in Helan Mountain area. They followed the trail and found a way: add lime, sulfur and saltpeter to the soil used for going back and forth to the grave, treat it at high temperature, and then smoke it with heat, so that nothing will grow.
The solution has been found, but it is not known whether it will work. So the grave diggers made a batch of such soil and planted some grass on it according to the way they found it. As a result, the grass soon hung. It really worked! Therefore, Cixi decided to use this method to build her grave. After the death of Cixi, the grave builder set up more than 100 large iron pots in front of the grave to stir-fry-no, stir-fry barren soil. Then use this soil to bury her grave.
