There is no doubt that Confucius has been a saint in China since ancient times, so is Wang Can Yangming called a saint with him? Personally, I think this is ok. Although Wang Yangming was born thousands of years later than Confucius, it did not prevent him from being called a saint.
Confucius is called a saint because he founded his own school. He is the most respected person in the world. At that time, he traveled around to give lectures and spread ideas. At that time, many other particularly famous and influential figures were invited by Confucius' thought. Moreover, the world was in chaos at that time, but Confucius still insisted on his lofty ideals and hoped to stabilize the troubled times on his own. Confucius' thoughts still affect people from generation to generation. Now we are still learning from Confucius' thoughts and being inspired by his famous sayings, epigrams and thoughts to face the problems in life.
And Wang Yangming is also a person with his own lofty ideals. He founded his own school "Xue Xin", which has influenced many people since its establishment and is regarded as the truth of seeing the world and seeing himself. In the history of China, Wang Yangming has always been an indisputable figure with great achievements and even immortality in virtue, contribution and opinion. Similarly, many people who are influenced by Wang Yangming's thought are also people who promote the historical process in history. Moreover, Wang Yangming's thoughts not only influenced China people, but also Japanese and Korean people, and they are still praising Wang Yangming's thoughts. So Wang Yangming is also a person who can be called a saint.
