以深海之名讨伐浅海之姓
[yĭ shēn hăi zhī míng tăo fá qiăn hăi zhī xìng]
'Yi Shen Hai Zhi Ming Tao Fa Qian Hai Zhi Xing' means 'In the name of the deep sea, I condemn (or fight against) the surname of the shallow sea.' It seems metaphorical and it might imply that this individual wishes to fight superficiality (the shallow sea) with authenticity (deep sea), depth (literally 'Deep Sea'). This could be someone who stands up against insincerity and values profundity in their lives.
