Is ancient China perilous?

Not really. If you go around slapping people's grandpas, then sure, it's a very dangerous place for you. But if you just do your own business, there's no real harm for you. People in ancient China (up to Three Kingdoms period) travelled all the time, most lived simple lives. Supposedly, people of Han lived satisfying lives. They weren't as affluent as we are today, but people could eat and could travel as they liked. It was only the later part of the Han dynasty that the empire declined and bandits could be found everywhere.

Then again, most wushia stories were set in the Song period, when literature flourished and sex mushroomed. The Song period was beset with political instability as new technology allowed formerly barren or mountainous lands to be opened for cultivation, thus allowing large communities to live in hidden mountains and valleys far from the cities of Song. That also allowed these hidden communities to end up becoming bandits and declare war on each other.

So was it dangerous travelling in the Song nation? Not particularly. Some of these hidden communities would put up road blocks and demand some kind of 'tax', sure, but if you can pay them, you'd usually be fine. Just don't go around slapping bandits in the face while saying, "HOW DARE YOU ASK ME FOR TOLL! I, YOUR FATHER WILL TEACH YOU MANNERS!" 

- Before Qind dynasty, china mainland consist of kingdoms, city states, and tribes region that make frequent skirmish war toward each other. Living as soldier at that time meant to put your life on the line. Food at the of war is varies but mostly it's either gruel or other mixed food so logistic not run out quickly. When campaign logistic has been used up soldiers can ask rice and other staple food from farmers, if farmers refuse soldiers still can raid their barn to gather rices as war provision. I don't about noble or goverment people at kingdoms is frequently doing alot of scheme or not, but laws of ancient times is kind of loosely and will be abused by higher up for their gain, some offical want to get nice ranking, and one of the fast route get that .

-Qin dynasty founder Qin Shi Huang tried to united mainland with war campaign and success. At some point on his reign he commanded to burn the books and burying the scholars.

- There's a lot of dynasties, Tang, Song, Han, Yuan, Ming, etc.
- Yuan dynasty enstablished by mongol people, an outsider people not from china mainland. A lot of citizen didn't like their goverment and so at this time many rebellion might happen until dynasty get destroyed by peasant uprising.

No matter the time period war always happened, living as lower class at that times tended not to be on the good side. Most of all, living at anceint time meant I can't get internet or scrolling on NUF 

The short answer is yes, and no.

The longer answer is that things in the past tended to less pleasant than they are now.  Even not counting modern conveniences, there are things like high infant mortality, all the women dying at childbirth, dangers from disease, the constant threat of starvation and malnutrition, and so forth.  Living in those eras was just a lot more unpleasant and fraught with challenges than TV and other media would have you believe.

And so the operative question isn't really whether living in ancient China was bad because living anywhere back in the day was bad.  The question is really about whether living in ancient China was worse than other places.  And generally speaking, it wasn't.  China was generally more prosperous and more advanced than just about any other civilization up until the modern era which was why it was able to sustain large populations and urban centers.  Sure it had famines and wars and other calamities, but these were present everywhere else as well.  At least China had the centralized government and bureaucracy to mitigate some of these problems while other peoples were mostly left to fend for themselves.  I think that one of the reasons why China may see worse off is that Chinese writers are less prone to romanticizing what their country was like in the past.
