Some of my students, especially those who come from English-speaking countries, are crazy about classical Chinese as it is too difficult to read and understand. Actually, it may easier to learn if you can master some key sentence patens like what I have summarized above.
北冥(míng)有鱼，其名曰鲲(kūn)。鲲之大，不知其几千里也；化而为鸟，其名为鹏(péng)。鹏之背，不知其几千里也；怒(nù)而飞，其翼(yì)若垂(chuí)天之云。是鸟也，海运则将徙(xǐ)于南冥。南冥者，天池也。齐谐(xié)者，志怪者也。谐之言曰：“鹏之徙于南冥也，水击三千里，抟(tuán)扶摇而上者九万里，去以六月息者也。”野马也，尘(chén)埃(āi)也，生物之以息(xī)相吹也。天之苍(cāng)苍，其正色邪(yé)？其远而无所至极邪？其视下也，亦若是则已矣。
“In the northern ocean there is a fish, called the Kun, I do not know how many thousand li in size. This Kun changes into a bird, called the Peng. Its back is I do not know how many thousand li in breadth. When it moves, it flies, its wings obscuring the sky like clouds. When on a voyage, this bird prepares to start for the Southern Ocean, the Celestial lake.
In the Records of Marvels we read that when the Peng flies southwards, the water is smitten for a space of three thousand li around, while the bird itself mounts upon a great wind to a height of ninety thousand li, for a flight of six months’ duration.
There mounting aloft, the bird sees the moving white mists of spring, the dust-clouds, and the living things blowing their breath among them. Is its azure the proper color of the sky? Or is it occasioned by its distance and illimitable extent? If one were looking down, the very same appearance would just meet his view.”
