两城决转身一世琉璃白
[liăng chéng jué zhuăn shēn yī shì liú lí bái]
'Decisive farewell in two cities turned around leads a lifetime of crystal-clear white'. This can mean parting with one beloved city (representing a past) leads to spending your whole new future ('life long', 'white' refers freshness/purity/uncertainty of new beginning).
