Yeah true. The Wikipedia page for zhuge nu actually mentions that it was primarily a self-defence weapon for women, not a battlefield weapon.
I find it amusing that the Wikipedia page for Huo Che makes no mention of the Korean Hwacha, other than in its “see also” section. That said, which one was done first seems…debatable, I wouldn’t feel comfortable coming down too strongly in favour of either one being the first.
The catch is that you’re signing up for a recurring subscription, and Audible plays the hard sell when you try to cancel your subscription.
(If you’re determined though, this can be great for you. I think I’ve gotten a total of 5 or 6 audiobooks for free from Audible thanks to their free first month and “please don’t leave” unsubscribe flow and “please come back” emails.)
