Kung Kangxi är den andra kungen i Kinas Qing dynasti. Han föddes 1654. 

Som den första kungen i Qing Dynasti dynastin hade Kangxis pappa svårt att dominera och kontrollera över ett nytt land då på den tiden*. Men** Kangxis pappa var en jätte mycket känslofull person. En gång i tiden dog hans pappas (kind of confusing, who? his fathers father? naaaah...) favoritkonbubin från av en sjukdom, det gick ... förryckt gjorde honom mycket ledsen och galen***. Till slut bestämde hans pappa (same here, could be confusing) sig för att bli en munk i ett vanligt tempel.****

* I guess you mean "at that time" when writing "då", but just using "då" in this case is somewhat confusing for a swede, since the actual year is not in the same sentence. I guess you're actually referring to 1654, which is in the sentence before. So, better safe than sorry: "at that time", which would indicate - in my mind atleast - "ahh, at the time of when the guy was born, at that year..." or you could skip "på den tiden" as well. I mean, he was the first king, right?, so, I guess maybe that's why he was having trouble..?

** You're not really suppose to start a sentence in swedish with the word "Men", if it's not so that your new sentence completely negates the previous sentence. In this case the father had some trouble ruling and controlling a new contry, and then you just state that he was full of emotions, which doesn't really explain or negate the previous sentence. If you'd like to keep your "men" I would suggest that you do it with a comma instead: "...på den tiden, men Kangxis pappa var.." - it doesn't make 100% sense though, since the first part of the sentence isn't explained or contradicted by the second part. You could just skip it. Start fresh: "..på den tiden. //new sentence// Kangxis pappa var en..." since what comes next corresponds to his feeling, not his troubles with ruling the country (as you have explained it! Even though I guess you maybe wanted it to refer to each other.)

*** I guess this is what you mean (galen = crazy). The word "förryckt" is not something I've heard before, and I'm 37 years old and a native speaker! Can you be both sad and crazy?? =)

**** Gramatically correct, but a "munk in a normal temple" sounds strange, aren't temples "normal" to begin with? Sure you didn't mean a NORMAL munk in a temple, instead of some kind of special monk.. And then I guess the word normal ("vanlig") would be substituted with "enkel" which means "simple" (like "nothing fancy, just plain simple"), so, like this: "Till slut bestämde hans pappa sig för att bli en enkel munk i ett tempel", you can also spicy it up a bit: "Till slut bestämde sig pappan för att bli en enkel tempelmunk".

There's nothing wrong this first paragraph, but it seems kind of backwards. You are writing about King Kangxi, which is the title of the document, then you write two small sentences about him, and then the rest of the paragraph is about his father. Kind of confusing. I don't even know his name! =)

I guess you're building something up for paragraph 2...

I så fall ... äldre då.*

Då pappan var borta var Kangxi tvungen att bli statschef. Han var då bara 6 år äldre, än vad pappan hade varit när han blev statschef.

Kangxi växte upp med hans* sin farmor. Han var mycket duktig och kunning när han blev tioåring. I Qing dynastin, Det fann** fanns det en grupp minoriteter som bodde i norra Kina, och de vilja ville inte bli kontrollade kontrollerade under av Qing. Kangxi started startade många krig mot dem och vann ängtligen till slut. Det här ... Kina då.*** eh?? I guess you mean: Dessa krig var jätteviktiga då de förenade Kina [på den tiden]. Kina blev ett jättestarkt land under hans administration. 很好！

* Sounds more natural in swedish.

** No comma.

*** I guess you mean that those wars joined China as a country?

I made some other small "särskrivning"-corrections: the fact that we tend to make up new words be combining two (or more!) words: "jätte starkt" => "jättestarkt", there's no space in between.

This mistake is called "särskrivning", and is a very common mistake. It could be quite amusing sometimes:
1a. "Vi har kulglass!" => "We have scooped ice cream!"

1b. "Vi har kul glass!" => We have fun ice cream!" - FUN ice cream? I wan't one! =)

2a. "Vi letar efter kassapersonal!" => We're searching for cashiers!"

2b. "Vi letar efter kassa personal!" =>We're searching for bad employees!" - What? Why!?!

Dessutom* Kangxi var dessutom bra på kalligrafi och [x] poem. Han redigerade** ett lexikon som heter Kangxi Lexikon. I modern tids Kina använder man fortfarande Kangxi Lexikon för att lära sig Kinesiska.***
Om du besökar Förbjudna staden i Beijing får du en chans att titta på Kangxis kalligrafier, och veta mer om den berömd kungen i Kinas historia.

* Changed places, sounds better, and paragraphs don't usually start with "Dessutom".

[x] = reading/writing? What was he good at? I guess you mean writing: [x]=[på att skriva], the word "poem" is not often used, the word "dikt" ("dikter" in plural) is more common. So, "...kalligrafi och på att skriva dikter."

** Did he really only "edit" a dictionary? If he is remembered for something he probably created it. "Redigerade" sounds a bit "too boring/small" to be remembered for, maybe you should use "skapade" (created) instead.

*** Nothing wrong with this sentence, but to start with "I modern tids Kina" sounds very strict/formal and doesn't really "roll of the tounge" (which we would like it to). Maybe change it to: "Nu i modern tid använder man fortfarande Kangxi Lexikon i Kina för att lära sig kinesiska." - please also note the word "för" here, which I added, and is important: "för att" = "to". "för att lära sig kinesiska" = "to learn chinese".

I like your text, and I learned something I didn't know before!

Please note that I'm a bit picky and a like to write long descriptions of everything..

Hope you don't get mad at me!

It was only the first paragraph which was a little confusing in my opinion, but I kind of understood it later on, when you introduced the fact the the guy you were writing about was kind of "forced" into the role as leades because of his sad and crazy (!) father..
