Never close your lips to those whom you have already opened your heart.
志向远大之人，必须谨慎选择自己所承担的任务，有才华之人，必须选择一个值得投靠的人。
智者和愚人都没有害，最危险的倒是智愚参半。
The stranger is an element of the group itself, not unlike the poor and sundry 'inner enemies'—an element whose membership within the group involves both being outside it and confronting it.
出自《道德经》，耳根在作品中多次引用
艺术不在于你看到了什么，而在于你让别人看到了什么。
