Why was china an important trading post to the British during the opium war and..?

Question:

and how did they feel about the foreign influence.?


Those are my two questions.
Right now in my history class we are learning about, The Impact of imperialism on china. And I really
need help on these questions.

Answer:

i'm pretty sure its because they were addicted to opium....badly addicted, too many chinese were hooked and its government wasn't happy about that. the british didn't care; it was huge profit, and they wanted to keep the money flowing. i think there was also a shortage of silver too, because china kept buying the opium and its silver was flowing out of the country...

but anyways, china has and always will ****ing hate foreigners (at least when they aint making china rich). cities like nanjing and hong kong are huge marks of national shame and memories (from people like british invaders, or the japanese). china wanted the english out of there but this just couldn't fight off the british and their superior technology/navy

you'll see a lot of these examples of Western-style countries harassing and exploiting non-advanced cultures for profit. like the spanish with all of mesoamerica
