身处深海却不知水有多深
[shēn chŭ shēn hăi què bù zhī shuĭ yŏu duō shēn]
‘身处深海却不知水有多深' means 'I'm in a vast ocean, yet unaware how deep the water can go'. One possible explanation lies behind could refer that even though a certain situation looks complicated and challenging there remains lots unknown beyond surface understanding waiting for discovery. Another reason maybe just because users themselves have fallen completely within this scenario that they fail realizing entire complexity.
