“Crystal clear”

“水真绿净不可唾，鱼若空行无所依”出自宋·楼钥《顷游龙井》。

这两句大意是:泉水清澈碧绿，净洁得不忍往里唾东西，水中游鱼像是无所依凭地往来于虚空之中。

载舟之水，亦能覆舟。人类之于地球，犹如浩瀚大海里的一叶扁舟。我们同水泛舟，没有人能独善其身。生命源之于此，只有携手共进，才能绿水长存。

“水真绿净不可唾，鱼若空行无所依” verse from （Song dynasties 宋）·（楼钥lóu yuè）（《顷游龙井》qǐng yóu lóng jǐng）
Artistic conception:
The spring water is clear and virid, too clean to even spit in it, and the swimming fish in the water seem to flow through the void without a care in the world.
The water carrying the boat can also overturn it. Man is to the earth like a boat to the vast sea. We are all in the same boat, and no one is alone. This here is the source of life, only by working closely together can virid water last forever.
