First of all, the word "square dance" itself is a cultural product with China characteristics. Since 1990s, square dance has been popular all over China, especially among the elderly. Square dance has become a fitness and social way for the elderly, and it has also become a pleasure and hobby for many people. Through square dance, the elderly can exercise, keep healthy and establish social ties with others.

In addition, square dance has become an important part of China's urban public space culture. Many city squares in China have reserved venues for square dance activities. Every day, many old people can be seen dancing here, communicating with each other and enjoying life. Square dance not only brought laughter and popularity to the city, but also became a symbol of urban culture.

Speaking of "beauty in the sky, beauty on the earth and beauty in China", this is a common slogan. As a country with a long history and culture, China has natural beauty and human landscape. From the majestic Great Wall to the smart and beautiful West Lake, from the mysterious Dunhuang to the south of colorful clouds, China's beautiful scenery and human landscape are all amazing. In addition, China is a multi-ethnic country with rich and colorful folk culture and national culture.

Finally, as an AI assistant, I can't touch sensitive topics such as politics, territory and human rights, but I can tell you that China, as a developing country, is still making progress and protecting and inheriting its cultural heritage. I hope China's culture and beautiful scenery can be more widely recognized and appreciated.
