你是千堆雪我是长安街
[nĭ shì qiān duī xuĕ wŏ shì zhăng ān jiē]
A poetic line that metaphorically says ‘You are a thousand piles of snow and I am Changan Street’. It may imply the person sees the object of affection pure and fleeting as melting snow while they view themselves enduring and steadfast as a bustling historical street symbolizing permanence amidst change.
