Most people like to name their sons with similar meanings and can form a pair. Therefore, it is impossible for Liu Bei not to consider this.
Based on this, it is speculated that the name of Liu Chan was probably influenced by Liu Feng's name.
I guess that the name Liu Chan was not only decided by Liu Bei himself, but was probably influenced by military adviser Xu Shu.
It is estimated that the situation at that time was like this:
Liu Bei: Xu Shu took the lead, and now my wife is pregnant. I want to give my future child a name.
Xu Shu: What's your name?
Liu Bei: My eldest son's name is Liu Feng. If I have a son, I'd like to name him Liu Guan, which means "closed".
Xu Shu: It's really good to combine the first name with the last name. But apart from it, it is not good for character.
Liu Bei: according to the military adviser, what is a good name?
Xu Shu: To match the seal of Liu Feng, it is much better to seal the gods and officials than to close them.
Liu Bei: Immortals are illusory. It is impossible to seal gods. If you seal officials, you have to rely on others. I don't want my son to live a life of watching others' faces like I do in the future.
Xu Shu: I see. I think of a word, which is in line with your master's lofty ambition.
Liu Bei: what word?
Xu Shu: Since ancient times, the supreme person is Mount Tai to worship Zen. The master has given his adopted son a name, and then named his second son Zen. Together, it means to worship Zen, which is in line with the master's lofty aspirations. Besides, just looking at the word Zen means quiet cultivation of Buddhism. Isn't it wonderful?
Liu Bei: What the hell is Buddhism?
Xu Shu: There is a folk story about the Romance of Gods, and Buddhism is the legendary western religion. When I traveled around the world, I came into contact with monks from Tianzhu. They paid attention to the word "Zen" when they cultivated themselves.
Liu Bei: The word "Zen" certainly has great beauty in self-cultivation, and "Zen" is also what I want. But if you can't close the Zen, isn't it ridiculous to name your son "close the Zen"?
Xu Shu: Your master worries too much. If things are not good, how many people in the world can know your master? Who will study the meaning of the master's naming his son? Since the master has achieved great things, he can't look forward to the future. Naming his son "Fengchan" can always encourage himself, which is extremely beneficial for the master to achieve great things.
Liu Bei: ok, that's settled.
