What does the word "Fiona Fang" mean?

Di Renjie's right-hand man is Fiona Fang. Every time I meet a case, Di Renjie will say, Fiona Fang, what do you think? Derivative meaning is a kind of pushing hand to express opinions, learning from others' opinions or putting problems on others, which is also a satire on the working methods of officialdom.
