As China's capital, Beijing is a city of contrasts, where ancient history meets modern development. The Forbidden City, Tiananmen Square, and the Great Wall are emblematic of China's imperial past, while the city's skyline now boasts some of the world's tallest buildings, reflecting its economic and political power. Beijing is a center for education, culture, and technology, hosting universities like Tsinghua and Peking University. The city's rapid urbanization, however, comes with challenges like pollution control and managing a population of over 20 million.
