What do you mean by sudden disaster?

A sudden disaster basically means a sudden change in the plot.

Example:

Just having dinner outside with my boyfriend, I seriously said to the male ticket, "I don't want to be your girlfriend!" " "

He asked why. I looked into his eyes quietly, and after a long time, I said, "I want to be your wife!" " "

My boyfriend slapped chopsticks on the table and looked at me seriously: "Believe it or not, you will see jokes later. I will break your legs sooner or later and support you for life!" "

Joke is a Chinese word, and the pinyin is xiào hua, which means something that makes people laugh.

Jokes are short in length, simple and ingenious in story, often unexpected, giving people a wonderful feeling of being suddenly enlightened. Most of them reveal absurd phenomena in life, which are ironic and entertaining. There are different tastes.

On June 7th, 2008, jokes were approved by the State Council to be included in the second batch of national intangible cultural heritage list.
