What should be preserved in our traditional culture and what should be discarded?

Before I answer this question, I should make it clear that the question itself is problematic. The questioner's meaning is probably this: in our history and traditional culture, what culture should be preserved and promoted, and what feudal dregs left over from history should be discarded. This may be the intention of his question. Because traditional culture is called culture, it itself is a nation's long-term accumulation of excellent things, since it is excellent things, it does not matter what should be retained, what should be rejected.

So I'll answer my revised question. As we all know, China is historically known throughout the world as the four ancient civilizations, which has many inventions that we are proud of as well as cultural traditions, and first of all, not to mention the four great inventions of China's ancient times, more than 7,000 years ago, Fuxi's creation of the eight trigrams of the first day, as well as Zhou Wen Wang's eight trigrams of the second day of the day and deduce the heavenly stems and earthly branches, the yin and yang and the five elements of the culture and so on, in our lives now at times, not to mention the fact that since Not to mention the various rules and regulations, etiquette, filial piety, fraternal duty, loyalty, benevolence, righteousness, integrity and shame since Confucius founded the Confucian school. In the long history, the diligent Chinese people have created countless splendid civilizations, ancient fine irrigation farming technology, as well as architecture, Chinese medicine, Chinese medicine, health, feng shui, magic, dress, poetry, calligraphy, painting, ceramics, and so many too many cultures need to be studied, carry forward. Because the more national is the more global.

Of course, in the long history, naturally and inevitably produce some bad feudal dregs, such as the human division of high and low, the feudal hereditary system under the rotten rotten life system, the emperor's three palaces, the rich class of three wives and four concubines, the feudal rulers in order to grasp the monopoly of the cultural and educational superstition, the landlords of the poor peasants of the oppression, exploitation, and so on.

Since my cultural knowledge is still shallow, I can't say it comprehensively. In general, the retention of the development of the working people's tradition of hard work, goodness, wisdom of the best qualities, to abandon the bad ideas of unproductive, lazy, superstitious, and bandits, thieves, prostitutes, gambling, drugs and other vices, and imperfections, I hope that you will be criticized and corrected.
