Sure, here are six key sentences from the famous Chinese essay "醉翁亭记" ("Record of the Pavilion of the Drunken") by the Tang Dynasty writer and poet, Wang Zhihuan:
"岁云暮、风雨变,而后知蓬蒿之盛衰。"
"臼井之盲、尧舜之逆,然犹未得其大者也。"
"余读此书、仰观明哲、俯察昏愚、忍俊不禁。"
"感时思遗、是以报颜之所获。"
"合昏老以属妻、书万死以对友。"
"方将休期、翻觉愈为欢。"
Would you like me to explain the meaning of any of these sentences in more detail?
