I often think that the meaning of "Hao" does not necessarily have to be mysterious, especially the Hao in calligraphy works, which represents one's own thoughts and is different from the Hao of monks. The title of a monk is given by the master, and the common name is not used. The title is given by outsiders, and the given name is given by the master. In Buddhism, the title given by a master represents the master's expectations for his disciples, so it is mysterious. For us lay people, the nicknames we pick represent our own pursuits, such as Bada Shanren, which means "mountain people who can't laugh or cry." This account represents his mentality of resisting the Qing Dynasty to the end and is his pursuit.
The nickname is also a means of comforting oneself. I once thought about taking a nickname for myself and calling it "the person who brushes characters", which means writing words without doing anything, but after thinking about it carefully, I feel that the meaning is shallow. , forget it. Women do not necessarily have to be particularly feminine when choosing a number. For example, Lin Xiu would call her Pinzhong, and if she was careless, she would call Pinzhong Saint. I think if it were up to me, the pursuit of tranquility could be called "non-flowing water". These three words represent "mindless mind". Enterprising people can be called "Zhui Yi Jushi" to express their pursuit of Zhang Xu's Yi.
This is also a personal opinion. The matter of naming is of great importance and should not be interfered with by others. Just ask a question and give it a try.
