世家那么大我只想你世界那么大唯独爱你
[shì jiā nèi me dà wŏ zhĭ xiăng nĭ shì jiè nèi me dà wéi dú ài nĭ]
A rather romantic phrase, meaning in simple terms - despite the huge world we live in, my heart is only thinking of you and loving you alone. It signifies the power of love amidst vast possibilities and distractions in life. It shows loyalty and exclusivity of feelings towards someone.
