What is the meaning of "knowledgeable person" which was sent to Miao Axe Wang Sheng by express delivery, and what is the meaning of hanging it now?

Because Miao Fu used Tangshan accent in this sentence, and a courier in the sketch program also used Tangshan accent before, which left a deep impression on the audience at that time.

So, Wang Sheng made some changes according to the scene situation, in order to achieve a better scene effect, and it became "these three princes have all sent express delivery before", which is called Xiangua.

The original knowledgeable person was probably followed by words like "Why (Wang Sheng) is the third prince with Tangshan accent" and (Miao Fu) Tangshan is near the sea ".
