There is a story in A Dream of Red Mansions in which a person is laughed at by Granny Liu.

Back to the 40th Shi Taijun's two banquets in the Grand View Garden, a passage in Jin Yuanyang's three-announcement tooth card order:

I saw a daughter-in-law standing there with a box, and a maid came up and opened the lid, which contained two bowls of vegetables. Li Wan took a bowl and put it on Granny Liu's desk. Xi-feng picked a bowl of pigeon eggs and put it on Mrs. Liu's desk. Grandma Liu stood up and said loudly, "Lao Liu, Lao Liu, you eat like an ox, and you don't even look up when you eat an old sow." Laughing up and down. Shi Xiangyun couldn't hold on, and a mouthful of rice gushed out. Lin Daiyu fell on the table with a smile. Alas, Baoyu rolled into the old lady's arms. The old lady smiled and hugged Baoyu, calling him a "sweetheart". Mrs. Wang smiled and pointed to Xi 'an, but could not speak. Aunt Xue can't hold on any longer. The tea in his mouth was sprayed on Tanchun's skirt. Pulling his wet nurse to rub his intestines, everyone in the underground bent down, some hid out and squatted and laughed, and some endured laughter to change clothes for their sister. Only Xifeng and Yuanyang supported her, but Granny Liu picked up chopsticks. She didn't listen and said, "The chickens here are also handsome, and the eggs they laid are small and strange." Amber gave a heavy pat in the back. Grandmother Jia said with a smile, "This must be Xifeng's business. Don't believe what he says. " Grandma Liu praised the small eggs and asked for one. Xi-feng said with a smile, "One or two taels of silver. Try it quickly, it won't taste good when it is cold. " Grandma Liu stretched out her chopsticks to clip them. There. People in the underground have already discovered it. Grandma Liu sighed, "One or two pieces of silver disappeared without hearing the noise." Everyone was in no mood to eat, and everyone looked at him and smiled. Jia added, "Now that you've taken out the chopsticks, you won't invite guests to dinner. It's all ordered by Feng Yatou, and it hasn't been changed yet. " People in the underground didn't prepare this dental chopsticks, originally. Similarly, I wore a pair of ebony inlaid with silver. Granny Liu said, "Gold and silver are not as good as our hands." "If the food is poisonous," said Xi-feng, "we'll try to take out the silver when we go down the mountain." Grandma Liu said, "If this food is poisonous, our food will turn into arsenic. Even if it is toxic, we will eat it all. "
