Hello, hello! Ni hao, dear language adventurers! Strap in because today, we’re going on a delightful journey to explore a Chinese idiom, or should I say, ChengYu – “想入非非” Xiǎngrùfēifēi. Grab your notebooks and pens, or just your curiosity, because we’re about to dive headfirst into the fascinating world of Mandarin idioms.

Now, let me take you back to my childhood.

Picture this: it’s a hot summer’s day in Taipei. The cicadas are singing, and the iced bubble tea in my hand is the only refuge from the sweltering heat. I’m sitting in my grandfather’s living room, his antique fan swirling lazily as he tells me tales of olden days. Each story, more fantastical than the last, and I, a wide-eyed child, am utterly engrossed, lost in a world of dragons and emperors. That’s when my grandmother, always the practical one, walked in and gently teased, “你又在想入非非!” – “You’re daydreaming again!”

It was then I was first introduced to the ChengYu, “想入非非.”

What Does “想入非非” Mean?

  • Traditional Chinese: 想入非非
  • Simplified Chinese: 想入非非
  • Pinyin: Xiǎngrùfēifēi
  • English: To indulge in fantasy
  • Description:  想入非非 describes the act of letting your mind wander, of daydreaming, or indulging in wild fantasies. It beautifully encapsulates that feeling of losing yourself in a daydream, lost in your own world of imagination and whimsy.

History of 想入非非

The idiom “想入非非” originates from Buddhist scriptures, specifically from the term “非想非非想處”. This term refers to the highest state that a Buddhist meditator can reach during their practice. This concept is found in the ninth scroll of the “大佛頂首楞嚴經”.

In this state of “非想非非想處”, the meditator is able to abandon their original thoughts, feeling as if all secular things and their own body and mind have disappeared. It signifies a state of contemplation that has reached a transcendent and unworldly level.

However, over time, people who used this idiom but did not understand the true meaning of “非非” have transformed the entire idiom to describe imaginations or thoughts that are detached from reality​​.

Modern Usage of 想入非非

In modern Mandarin, “想入非非” is used to describe someone who is lost in thought or daydreaming, often with a touch of gentle teasing. For example, if your friend is staring into space during a conversation, you might playfully nudge them and say, “你在想入非非吗?” – “Are you daydreaming?”

This idiom is also used in more formal contexts to describe someone who is not being realistic or practical, often in discussions or debates. So, if someone proposes a plan that seems overly ambitious or far-fetched, you might hear someone say, “他的想法完全是想入非非” – “His ideas are completely unrealistic.”
