There are many ways to cultivate professional ethics. In addition to the above professional ethics, there are: (1) learning professional ethics norms and mastering professional ethics knowledge. (2) study hard modern scientific and cultural knowledge and professional skills to improve cultural literacy. (3) Self-reflection is often carried out to strengthen self-discipline. (4) Improve the spiritual realm and strive to be "cautious and independent". The word "cautious independence" comes from China's ancient book The Book of Rites, The Doctrine of the Mean: "Those who are Tao can't leave it for a moment, and those who are not Tao can leave it. An accident gentleman should be careful not to see that fear is almost unheard of. Don't see it hidden, don't show it, so the gentleman is cautious. " This means that moral principles cannot be left for a moment, and we should always check our actions. A moral person will be careful not to do anything immoral when he is alone and unsupervised. While advocating "cautious independence", we also advocate "accumulating goodness into virtue". Is to carefully safeguard their good deeds and let them continue to accumulate and grow. Xun Kuang, a philosopher in the Warring States period in China, once said: "Accumulated soil makes mountains, and it flourishes according to local conditions; The water drops merged into the ocean and the dragon was born; Accumulate goodness into virtue, the gods are complacent, and the sacred heart is prepared. Therefore, you can't take Wan Li Road without accumulating steps; If you don't accumulate a small stream, you can't become a river. " Noble moral personality and moral quality can not be cultivated overnight, it needs a long-term process of accumulating goodness.
