After meeting Cai Fei, Du Yuheng was attentive, and tried to trick Cai Fei into leaving with him by lacing his words with false sincerity, claiming that Aunt Mei had been sent elsewhere by the country's duke and that he would take Cai Fei to her. However, Cai Fei refused to fall for his tricks and refused to leave with him. Du Yuheng became impatient, so he directed two servants to drug Cai Fei with a handkerchief laced with an intoxicating scent. He then used the opportunity of no one supposedly noticing to secretly transport her away from the mansion through a back gate.
Although they said no one noticed, it was in bright daylight. How could no one notice within the spacious Duke An Mansion, where hundreds of maids and servants are moving about? It's just that everyone wisely pretended not to see what was happening.
