"Life is like a coffee table, full of tragedies and tableware." First of all, in the first issue of Lecture Room, Yi Zhongtian sighed "tragedy" with wide eyes. The result was cut off by netizens and uploaded to the Internet, which immediately became a signature document cited by countless netizens. In fact, the sentence template of this catchword comes from Zhang Ailing's pen-"Life is a gorgeous robe full of lice."

After the word "tragedy" was born, a "tragedy party" appeared on the Internet, and netizens created "tableware (tragedy)", "washing utensils (comedy)" and "tea set (gap)".
