Why does Lin Daiyu call Grandma Liu a "mother locust" in "A Dream of Red Mansions"? What is her purpose?

I personally think this is just a joke by Lin Daiyu, basically without any deep meaning. Of course, based on the background at the time, I think it may be to lighten the atmosphere and make the scene less embarrassing. Then Next, I will tell you about these plots in detail.

Then let me first show you a small fragment from Dream of Red Mansions. Daiyu smiled and said: "It's all because of the old lady's words yesterday, asking him to draw some garden pictures, which made him so happy that he asked for leave." Tan Chun said with a smile: "Don't blame the old lady, it's all because of Grandma Liu's words Lin Daiyu laughed quickly and said, "But it's all his words. He is a grandma of that kind. Just call him a 'mother locust'" and everyone started laughing.

This is when Xue Baochai really started laughing, because everyone should know better that Xue Baochai has a very mature and steady personality, and is generally unsmiling, so in order to make everyone laugh, our sister Lin A very humorous joke. Although many people still don't understand and think this is to clear Lin Daiyu's name, then I will give you the evidence.

Indeed, many people may think that we are whitewashing Lin Daiyu, but it is true that Lin Daiyu was just making a joke and never had any other meaning. You will understand after reading the next chapter.

The original text reads like this. Baochai smiled and said: "All the words in the world are gone when they reach Feng Yatou's mouth. Fortunately, Feng Yatou doesn't know the characters and is not very proficient, but it's just the common custom in the city." Making fun of him. What's more, he used the "Spring and Autumn" method to summarize the vulgar words in the market, cut out the complex ones, and added embellishments and metaphors, one sentence after another. All the scenes from yesterday appeared. Fortunately, he thought quickly."

Okay, let me summarize it for everyone. Lin Daiyu was just making a joke, nothing else. mean.
