海蓝不及你心
[hăi lán bù jí nĭ xīn]
The phrase 'Hai Lan Bu Ji Ni Xin' translates to 'The blue sea cannot compare to your heart'. It expresses admiration for someone's depth of character or inner beauty, indicating that no matter how vast and deep the ocean is, it still falls short when compared to the depth of that person’s emotions or soul.
