《庄子·内篇·齐物论》
林泽焚烧不能使他感到热，黄河、汉水封冻了不能使他感到冷，迅疾的雷霆劈山破岩、狂风翻江倒海不能使他感到震惊。
大泽焚而不能热，河汉冱而不能寒，疾雷破山、飘风振海而不能惊。
He doesn't feel heat when the forest is burning, he doesn't feel cold when the Yellow River and the Han River are frozen, and he doesn't feel shocked when the thunder splits mountains and rocks, or the gale turns rivers and seas upside down.
