`上当` is a cornerstone of daily conversation in China, reflecting a common societal awareness of scams, tricks, and the importance of being cautious. In a rapidly developing economy, new types of fraud (telecom, online, investment) are frequently reported in the news, making the concept of `上当` highly relevant.

A very intelligent and cautious person can still `上当` if the scheme is clever enough.

Therefore, people will often warn each other, “小心,别上当!” (Be careful, don't get tricked!), highlighting a cultural value of street-smarts and vigilance in navigating social and commercial interactions.
`上当` is used constantly in informal and semi-formal situations.
