First, the eldest son has existed since ancient times, not to say that it was changed to "constant" for taboo. The evidence is that the eldest son is a surname, and the origin of the long surname can be traced back to the era of the Yellow Emperor 5,000 years ago ("The Origin of Surnames" said: "The Yellow Emperor made the long barbarians occupy the moon, and sometimes it was the first, so the long surname should be based on this). So the original Tao Te Ching was like this. Why should it be changed now? In other words, the original text of Tao Te Ching is like this. In order to avoid it in the Eastern Han Dynasty, it will not be changed to the word "Chang" because the original text is a word "Chang".
Secondly, if the word "constant" in Tao Te Ching is replaced by the word "constant", it is unwilling. Because the desire of the Bible is an abnormal Tao and an abnormal name, that is to say, that kind of Tao and name is not the usual Tao and name, and it is the same as the rhetoric of ordinary people. If you change "constant" into "constant", the meaning will change. Imagine the meaning of "extraordinary Tao" and "extraordinary name": it is not an unchangeable Tao, not an unchangeable name. Where is this the same as the original intention?
To sum up, "the first sentence of the original Tao Te Ching that can be found on the Internet now is actually an extraordinary Tao, a name that can be named extraordinary?" This situation is normal, because the Tao Te Ching was originally like this!
I hope the landlord understands!
