提速

Usually, you use it as a verb. You can say a project needs to 提速. You can also say a train is 提速-ing. It often appears in professional settings. However, friends use it when they are running late too. It is a very 'action-oriented' word. Use it when you want to see progress happen quickly.

Use it during a meeting when a deadline is close. Use it when talking about China's fast-growing infrastructure. It is perfect for texting a friend who is walking too slowly. It fits well in news reports about technology. If you are talking about self-improvement, it works there too. It sounds modern and efficient.

Don't use it for physical objects falling down. That is a different kind of speed. Don't use it for someone's heart rate. That would sound like a medical emergency. Avoid it in very poetic or ancient contexts. It is a modern, 'fast-paced life' kind of word. It might sound too cold for a romantic moment.

China is famous for its 'China Speed.' The phrase 提速 became a household term during the national railway upgrades. Between 1997 and 2007, China had six major 'Railway Speedups.' This changed how people traveled across the country. Now, the word represents the country's obsession with efficiency. It carries a sense of national pride and modern development.

If you want to be more casual, use 快点. If you are talking about a car, use 加速. 提速 is specifically about raising the existing limit. You might hear 全面提速 which means speeding up everything. People also use 给生活提速 to mean living a more intense life. It is the go-to word for 'leveling up' your pace.
