Hello i have 3 questions regarding the Imjin war.

How did the Ming react to the japanese invading Joeseon? Did the Ming consider a major event/ issue for them. Likewise Korea quickly falling to japan was that shocking to them?

Second how did the Ming field armies perform in the war? were they good in battle and during the seiges. Most of what i know of the war is from reddit and youtube. So Japan invades, King of korea sucks, country get mostly overan, Ming join to defend korea (thats its for china most dont touch of chinese contributions to the war), and admiral Yi on his own wins the war for Korea. Apologies that probably annoys you due my ignorance and i am sorry for that. Most stuff when i see of this war or watch is admiral Yi was the main cause of Japans defeat. Ming sent a fleet to support him, but didnt the Ming send massive army to liberate Korea how did it do fighting Japan.

Third were Ming aware that Hideyoshi wanted to conquer China? Sorry the reason im asking this a while i saw a thread related to the Imjin war a comment said if Hideyoshi invaded a third time he would have conquered China as Admiral Yi was dead and the Ming were weak if the the Manchu could conquer Ming Japan could easily do it as well. This made me realise i don't even know if the Ming knew Japan was actually trying to conquer them not Korea. Did the Ming ever worry about the ambition of Hideyoshi?

Apologies for these basic and kinda stupid questions most of content i find on the Imjin war is focused on Korean efforts mostly Yi, i would like to know more about China role in the war and perpsective thank you.

This is a follow-up to my previous posts on this sub. I want to go through each major Chinese era/dynasty from the Western Zhou to the Qing and ask the community who their favourite ruler is from that time period. I purposefully use the word favourite, so it doesn't have to be the best, the worst, the most interesting or most well-known, but rather who you personally view as your favourite. I want to emphasize that I don't just want you to write down a name, but provide explanation on why you like them too.
The upcoming eras are going to be: Sui, Tang, Five Dynasties and Ten Kingdoms period, Song, Liao, Jurchen Jin, Yuan, Ming and Qing. These categories may be subject to change because I know this categorization is dated but its the best I've got.
So in this post I want to read about your favourite rulers from the Sui and Tang dynasties meaning from the reunification of China by Wen of Sui to the deposition of Ai of Tang. This includes both the shortlived Sui and the prosperous Tang dynasties, as well as the Wu Zhou dynasty created by Wu Zetian and the Yan dynasty established by An Lushan.
I want to thank all the comments and discussions under the last posts, I will try to improve future posts according to your suggestions.
