" from generation to generation" or " from generation of generation"

The importance of traditional culture
Traditional culture is shared experiences that are transferred from generation to generation. They can exist at the level of a nation or community and can transcend borders.
Chinese traditional culture is one of the world's oldest cultures, originating thousands of years ago.
Economic globalization has brought about cultural diversity in China. As a result, many young people prefer to celebrate Christmas, Valentine's Day and other Western festivals to traditional Chinese festivals such as Dragon Boat Festival.
Competition among countries today is no longer a simple affair. It transcends economics and military might, and includes cultural soft power. Some developed countries are using their cultural soft power to the hilt to promote their values and ways of life across the world.
Under such circumstances, it is essential for China to strengthen the influence of its traditional culture and enhance Chinese people's sense of identity and national pride.
