你是我飞不过的沧海
[nĭ shì wŏ fēi bù guò de cāng hăi]
Derived from classical Chinese literature and poetry where vast bodies of water often represent insurmountable obstacles. The username expresses profound unattainable yearning for something that cannot be reached or overcome by oneself ('You are my unflyable Cang Hai' - a sea too wide to cross).
