The Dongchuang Incident

Pinyin: dōng chuāng shì fā

Explanation: The plot planned under Dongchuang was reported. It means that the conspiracy is exposed and you will suffer the consequences.

Source: It is said that when Qin Hui killed Yue Fei, he and his wife Wang made plans under the east window. After Qin Hui's conspiracy was exposed, he was arrested and imprisoned. He suffered in prison. The Wang family gave him a Taoist temple and sent Taoist priests to visit him. He said to the Taoist priest: Please tell Madam that the conspiracy under the east window has been exposed. Later, he used metaphors such as "Dongchuang incident occurred, Dongchuang incident occurred, and Dongchuang incident occurred" to describe the conspiracy being exposed and being punished.

Because the conspiracy was under the east window, the incident happened under the east window.
