《资治通鉴·宋纪·宋纪九》
如果办不到，还可以自己率领归附正义的人，仔细选择水路和陆路的交通便道，全身而退，逃往南方，这也不失为中策。 
如其不能，可躬帅向义之徒，详择水陆之便，致身南归，亦其次也。 
if we fail to do this, we can still personally lead those who have come over to the righteous side, carefully choose the convenient waterways and land routes, withdraw intact, and escape to the south. This would also be a middling plan.
