I was discussing a linguistics paper about chengyu in one of my YouTube videos and wondered what is the most common chengyu. It's the kind of question someone like me would like to know off the top of my head. But I don't know...
I Googled the question in English and Chinese, and found lists of common chengyu, but these are based on people's subjective impressions, and not actual data, and nobody says which is the most common chengyu, just e.g. "here's 100 common chengyu".
Question: Which is the most common chengyu (idiom)?
I feel like this is the kind of thing someone should already know. I really can't guess which is the most common chengyu; perhaps it's 不可思议 or 乱七八糟.
