What is the connotation and core of China's traditional cultural heritage?

I think the core idea of your China traditional culture inheritance is that you must be filial, because I think filial piety has a long history, and China culture has a history of 5,000 years. I think filial piety comes first, because I think a person who treats his parents well, respects them and knows how to be filial will make a difference in society. Zhu Dexiao comes first. I think a kind person should be very filial to his parents first, because China was filial to his parents in ancient times. He is very successful, so in the core concept of China traditional culture, filial piety is very important.
