《后汉书·列传·方术列传下》
赵炳于是故意登上茅屋，用梧树干支撑着锅煮东西吃，主人看见了大惊，赵炳笑而不答，不久菜煮熟了，屋没损坏。
炳乃故升茅屋，梧鼎而爨，主人见之惊懅，炳笑不应。既而爨孰，屋无损异。
Zhao Bing therefore deliberately boarded the cottage, using elm tree trunk to support the pot to cook, the owner saw it with great surprise, Zhao Bing laughed but didn't answer, not long afterwards, dishes were cooked, the house was not damaged.
