Who is the prototype of Gui Wang's meritorious works?

In the TV series "Meritorious Service", Wang Gui caused Yuan Longping a lot of trouble after his appearance. The role of Wang Gui is based on the real prototype, and the real prototype and Yuan Longping once studied rice together. Although Wang Gui has always been an enemy of Yuan Longping in the play, Wang Gui sincerely wishes Yuan Longping in the final plot and appreciates Yuan Longping very much.

Note: Wang Gui introduced himself when he appeared. He is the director of Anjiang Agricultural School. Wang Gui has been a bureaucrat since he appeared. King Gui used his position as director to instruct Yuan Longping, Tan Panggong and others. Although Wang Gui is the director of the agricultural school, he doesn't know the inside story of scientific research or the knowledge about rice. Wang Gui is a very conceited person in the play. He often points fingers in front of many scientists.

When Yuan Longping announced the plan of sweet potato king, posters attacking Yuan Longping appeared on the blackboard. This poster is about a gentleman, and this gentleman is Wang Gui. Wang Gui repeatedly condemned Yuan Longping under the pseudonym of a gentleman.

At the beginning of Wang Gui's debut, he hoped that Yuan Longping could get scientific research results, adding luster to his face as the director of the agricultural school. Yuan Longping published a paper on the failure of the sweet potato king plan, which made Wang Gui's face ugly, and the two men also had an argument because of it.
