Standing on the shore gazing out, sea and sky one color - truly 'none knows how many thousand li it stretches.'
Tips
history
From 《庄子·逍遥游》 opening (Zhuangzi, 'Free and Easy Wandering,' Warring States, c. 300 BCE): 北冥有鱼，其名为鲲。鲲之大，不知其几千里也 (In the Northern Ocean there is a fish called Kun. Kun is so vast that nobody knows how many thousand li it measures). The fish then transforms into the Peng bird and soars south - the founding image of Daoist cosmic perspective.
usage
也 is a classical final particle marking assertion (not 'also'). Reading: 几 = jǐ ('how many'), 3rd tone. Usually quoted in context with 鲲之大 or 其翼若垂天之云. A stock phrase for boundless scale.
