There has always been an unsolvable mystery in the TV series " The Legend of Zhen Huan ", that is, who poisoned Shen Meizhuang ?
In fact, there are three suspects in total, one is the queen, one is Concubine Hua , and the other is Concubine Jing .

It is impossible for the queen to poison Shen Meizhuang. The main reason is that the queen's main purpose is to have an abortion, and the other is to prevent the concubine from becoming the next Chinese concubine. Shen Meizhuang has lost power, and the Queen's understanding of Shen Meizhuang makes it impossible for Shen Meizhuang to have emotional sustenance for Big Fat Orange, so the Queen cannot take action against Shen Meizhuang.

It is impossible for Concubine Hua to poison Shen Meizhuang. The main reason is that Shenmeizhuang's fake pregnancy to compete for favor was originally instigated by Concubine Hua. Concubine Hua wants to prove Shenmeizhuang's fake pregnancy and compete for favor. What she has to do now is to get rid of all the witnesses and let Big Fat Orange take action to get rid of Shenmeizhuang. She would wait until the whole thing calmed down before she would take action to remove Shen Meizhuang.

After eliminating the two big bosses, the Queen and Concubine Hua, Concubine Jing became the only suspect. Why did she take action against Shen Meizhuang?
First of all, she and Shen Meizhuang have a community of interests. Shenmeizhuang is a concubine in Concubine Jing's palace. If anything happens to Shenmeizhuang, Concubine Jing will naturally be involved. Instead of feeling anxious, it is better to take a risk and muddy the waters. So Concubine Jing poisoned Shen Meizhuang.
Secondly, Jing Fei has many opportunities to commit crimes. Firstly, she lives with Shenmeizhuang, secondly, Shenmeizhuang is under her jurisdiction, and lastly and most importantly, Shenmeizhuang especially trusts her. So she poisoned Shen Meizhuang, and Shen Meizhuang would not doubt her.

Concubine Jing is indeed very smart. She not only completed the task of poisoning, but also exposed it in front of Shen Meizhuang. She sold Shen Meizhuang a favor, and also removed herself from Shen Meizhuang's fake pregnancy to compete for favor, and established Shen Meizhuang's fake pregnancy to compete for favor. In this way, her life as the lord of the first house will be easier.
