So My Whole Family Is an Expert?

The house is really messy. My grandma used to play tricks all day long, making me drink fragrant ash water, and telling everyone there was something dirty in their house. Dad doesn't go to work during the day, and locks himself in the study at night, claiming to be staying up late to cultivate. My mother never cooks, and she nicknames herself the White Magician. She paints messy paintings on the floors and walls of the house. Grandpa was even more trouble-making. Ever since he started practicing Tai Chi, he thought he was a master. He would fight with people in the community park every day, especially old men in their 70s and 80s who had difficulty moving. He never lost a single fight. But I was miserable, having to apologize as a grandson to half of the community. That day, I finally couldn't stand it anymore and decided to pretend to be an old man and educate my grandfather. But what I never expected was that grandpa dodged my attack with one move of 'Tiyunzong' and flew above my head... Only then did I realize that my entire family is an expert?
