Tomato and egg stir fry
This is a meme referring to the recent "tomato and egg stir fry" incident, featuring SNH48 singer Li Yitong, a journalist who didn't do his homework, and a bunch of collaterally damaged Chinese Touhou fans.
On Mar.4 2019, Li hosted her birthday fan meeting. Being a long time ACG fan, especially Touhou Project, Li cosplayed Flandre Scarlet. However, the entertainment journalist who reported on this knows absolutely nothing about anime, let alone Touhou characters. In his article, he described Li's cosplay as "cheerfully colored clothing with a theme of tomato and egg stir fry, along with crazy wings that swings whereever it wants."
Of course, Chinese Touhou fans didn't take this lying down. Using Naga u's kemomimi-chan as the basic template, Tomato and egg stir fry Flandre memoticon came first, and other food themed Touhou character memoticons soon followed. Currently they are working on forcing a food theme on every single Touhou character.
