大眼看世界小眼守爱情
[dà yăn kàn shì jiè xiăo yăn shŏu ài qíng]
This interesting nickname suggests looking at the big wide world with open eyes, meaning being observant of what's around, while using another look, metaphorically represented by 'small eyes' which might suggest intimacy or close observation, when it comes to protecting or appreciating love.
