You see it a lot in space conversations because it covers planetary gravity in an interesting way.
It is, somehow, very bleak and pessimistic compared to your average (western?) sci-fi.
I started reading the first book before I started using this method, and abandoned the series a couple times but saw it coming up so often in sci-fi recommendations I kept wanting to get through it
I found the first half of book one elicited no interest in reading in my down time, but was just barely interesting enough to not quit listening.
By the second half of book one and the entire rest of the series (plus the author approved fan fiction fourth book) I completely gave up on the audiobook because the story was so good that I wanted to read it as quickly as possible. I actually switched to reading on my phone in the shower over listening.
It starts off slow but gets good and stays extremely good. One of my favorite series.
Otherwise it'll be like drinking from a firehose.
I don't know, I lived in China for 9 years, and scifi and fantasy media were highly discouraged by the party (as mentioned in the wiki link), and no one I knew had anything to recommend that was originally written in Chinese. When Three Body Problem came out, people went nuts. Every nerd and engineer in the country read it.
There's the rub. Access to the world's cultural resources is highly limited in China. They've outright firewalled the internet.
Liu's writing is incredible, but he reminds me of George RR Martin or.....bare with me..Vince McMahon. Unable to get beyond the "fleshing out" phase.
The standalone book Old Man's War is also incredible.
And of course....Hyperion is the king of the entire genre. If you haven't read those I'd highly recommend it, will change your life.
If you go in expecting adventure fiction, then it's not enjoyable. It's more like reading something like Olaf Stapledon.
