摺紙鳥為什麼那麼大？

Missing, extremely new, or very obvious to obtain.

A reference to an old Chinese meme "Why is the pigeon so huge?" It was used to point out the situation when someone asks the question yet refuse to listen to an explanation. It started when a Korean posted a photo of an extremely big pigeon (due to perspective) on a forum, which subsequently attracted numerous comments from netizens. One enthusiastic person patiently explained the logic to them, even drawing diagrams and 3D models, yet the questioners still replied with: "I understand the reasoning, but why is the pigeon so huge?" It made the guy rage quit. - Credit: Necrosyrtes
