What are the four guards who eavesdrop on Shu Fangzhai's mouth in Princess New Zhu Huan? Which movie and which episode do they play?

The first floor. Yes, it is. At that time, Wei Zi had just entered the palace, and they were not at ease. They also shook hands with the queen's eyeliner.

Episode 19

Talking to my biological father for the first time, Wei Zi felt warm and happy. Zheng Xiaoyan and others are having fun, but Mammy Rong is watching secretly. At night, Swallow and others were drinking happily in Shufangzhai, and Yongqi, Benmingjie, Erkang and Ertai came to the door to guard. Sure enough, a man in black broke into Fang Shu Zhai at night, and the two sides met, and Erkang and others saw the identity of the newcomers. The men in black fled and reported the movement of Shu Fangzhai to the queen. The queen told them to keep their mouths shut and continue to send people to spy on Shu Fangzhai.
