The act of 升旗 (shēngqí) is a deeply significant ritual in modern China, acting as a constant and visible reinforcement of national pride and unity. The most iconic example is the daily flag-raising ceremony in 天安门广场 (Tiān'ānmén Guǎngchǎng), Tiananmen Square, in Beijing. Performed by a specially trained, elite guard of soldiers, the flag is raised precisely at the moment of sunrise and lowered at sunset. Thousands of tourists and citizens gather in the pre-dawn cold every day to witness this solemn, highly choreographed event, which is also broadcast nationally. It's a powerful symbol of state power, national dignity, and collective identity. This can be contrasted with flag-raising in Western countries like the United States. While Americans display patriotism by raising the flag at homes, schools, and sporting events, it is often a more decentralized and individual act. The Tiananmen ceremony, by contrast, is a centralized, state-run ritual that the entire nation can watch and participate in vicariously. It reflects a more collectivist value, where patriotism is expressed through shared, organized, and uniform public ceremony. In China, especially for the younger generation, the weekly school 升旗仪式 (shēngqí yíshì), or flag-raising ceremony, is a formative experience that instills a sense of national identity and discipline from an early age.
升旗 (shēngqí) is used in formal and official contexts. It's not a casual term.
The connotation is always one of solemnity, respect, and seriousness. Joking during a 升旗 (shēngqí) ceremony would be considered highly inappropriate.
