What is Dai Xingyang?

The funny stem comes from the TV series "Please call me a director". In the TV series, Ning Meng, the female host, became the acting secretary of the male host, and some colleagues called her "Dai", while the female host joked about the words of Dai Secretary, my surname is Yang and Dai Xingyang, thus forming a funny stem. Based on the novel of the same name, the play tells the story that Ning Meng, who dreamed of becoming an investor since he was a child, mistakenly became the president's secretary, fought wits with the super-capable and hot-tempered Pakistani boss Lv Biming, and finally joined hands to realize his dream and do business side by side.
