Why did Feng Shui master fool Cixi into cutting down the ginkgo tree in front of Guangxu's father's grave to win his favor?

Empress Dowager Cixi, the ruler of China in the late Qing Dynasty. After the death of Emperor Tongzhi, the only son of Xianfeng, Cixi adopted Yi Xuan's son Zai Tian to Xianfeng, the later Emperor Guangxu, in order to continue her power and rule. However, after Yi Xuan's death, Cixi listened to the rumors of Feng Shui master and cut down a white fruit tree on Yi Xuan's grave, completely ignoring the feelings of Emperor Guangxu. Why?

Let's talk about why Cixi immediately became Emperor Guangxu. She is neither her own son nor Xianfeng's son. It is because Guangxu and Cixi are actually close relatives. First of all, Guangxu's father Yi Xuan is Xianfeng's half-brother, and Guangxu's mother Ye Henala Wanzhen is Cixi's own sister. So Guangxu is both the nephew of Cixi and the nephew of Cixi. With this relationship, Cixi can continue to take charge of state affairs in a proper way.

Later, due to the increasing influence of Yi Xuan, there was a great contradiction between Cixi and them, which also affected the relationship between Cixi and Guangxu. After Yi Xuan's death, a tall ginkgo tree grew in his cemetery, which covered the whole cemetery with several acres of huge shade in Fiona Fang. Li, the eunuch around Cixi, was proficient in Feng Shui and said to Cixi, "Wang Jiabai is the emperor, so it can be seen that some of the descendants will be kings." Hearing this, Cixi immediately ordered the ginkgo tree on Yi Xuan's grave to be cut down.

But it's a matter of digging your own grave. How could Emperor Guangxu agree to treat his late biological father like this, so he insisted on not cutting down trees. But later, Cixi personally took people to the cemetery at dawn. Guangxu rushed to chase after knowing it, and even dug up the roots when he arrived. Everyone said that the queen mother cut three axes before she cut it. Guangxu was speechless and had to go back dejectedly.
