The vinegar tasters
In the picture it can be seen three men dipping a finger in a vinegar pot and tasting it. One of the men reacts with a sour expression, other reacts with a bitter expression and the last one reacts with a sweet expression. The three men are representations of Confucius, Gautama Buddha and Laozi and represent the three greatest Chinese philosophical traditions and the predominant attitude towards the life of each one of them.
