彼此站在两个世界
[bĭ cĭ zhàn zài liăng gè shì jiè]
'Standing Each Other From Two Different Worlds'. Here, it expresses a sentiment that there exists a fundamental gap between two hearts or beings which may stem from divergent views, social strata, or different pursuits in life. Despite being close physically or emotionally, this vast psychological distance still looms over them.
