江山如画一时多少豪杰人生如梦一尊还酹江月
[jiāng shān rú huà yī shí duō shăo háo jié rén shēng rú mèng yī zūn hái lèi jiāng yuè]
A famous verse saying the beautiful view like rivers and hills witnesses all heroes over the history; and looking forward into infinite past and future generations, human life seems to vanish as quickly as a dream. It's profound to convey the insignificance of mankind in comparison with the vastness of nature, as well as lamentations or regrets about fleeting moments of grandeur and glory in one's own existence.
