Because the ancients generally had their own routines when writing essays, and people are used to their specific thinking patterns, so there will be certain ambiguities in some of them, otherwise there would be no literary inquisition. But generally speaking, the education they received from childhood was in that style of writing, just like we are used to sentence fragmentation today.

At the same time, the lack of punctuation also adds a meaning to the article. Of course, this kind of meaning is not something that people who read today want to understand because it is too troublesome and complicated.

It is not that the ancients did not do business. Although there were several dynasties that focused on agriculture and suppressed business, it is impossible that there was no businessman, and they did not lose everything.

So they don’t use punctuation just like we do.

When it comes to signing a contract or a letter, I think the parties involved will carefully consider it and try to avoid any ambiguity. In ancient times, traditional Chinese characters were used for writing, and Arabic numerals were not used like today. A single dot will produce different results, which is why signatures in traditional Chinese are now required internationally! So it is not impossible to find faults in the eggs, so it depends on how the ancients dealt with it!
