莫失莫忘相思苦相濡以沫忘江湖
[mò shī mò wàng xiāng sī kŭ xiāng rú yĭ mò wàng jiāng hú]
A classical style phrase: 'Never forget never lose, even though missing you torments me like the two who support each other with saliva should forget the jianghu (chaotic and competitive environment full of tricks and danger). Here jianghu means an ancient society outside formal political authority.'
