As the name implies, a winemaker is the person in charge of brewing wine. As we all know, Liangshan heroes love to drink. It can be said that there are no people in Liangshan who don't drink, but we assume that if the winemaker in Liangshan poisoned the wine and then gave it to the heroes, we all know that Sun Erniang and Song Wu were cheated in this way. If it happens, the consequences can be imagined.
War horse is a necessary item in ancient traffic and war. In ancient times, horses were very important for marching and fighting. A good horse can decide the success or failure of a battle, which is also the most important reason why Ma Jun went to Liangshan. If a veterinarian often deals with horses, lays hands on them and infects them with infectious diseases, then the fighting capacity of Liangshan can be seriously weakened.
We know that the slogan of Liangshan heroes is "Let's drink together and eat meat together", so basically every meal will use a lot of food. Of course, this is also indispensable. Food management in Liangshan is also very popular. But think about it, if the person in charge of this work put poison into the dish, Liangshan is estimated to have been killed overnight. If these three positions are not made by people around him, it can be said that it is a disaster in Liangshan.
