I like Germany

On May 2013, I travelled to Germany. I like the country. Beacuse I think Germany is a great country. There are beautiful bulidings (all kinds of houses and churches) and kind people. Germany is one of the most advanced industrial country. Chinese should study for Germany about the technology and the serious and strick. I like its big green fields. I heard that the county will be more beautiful colorful in autumn. I'm looking forward to visit the country again in autumn.

I like Like (titles should be in all caps except for words like: the, a, and, etc.) Germany 

On In (you would use "on" if it was on a specific day, but since a month is a range, just use "in) May 2013, I travelled the to Germany. I like the country. Beacuse because (connect the two thoughts as one sentence because they are related), and you shouldn't start sentences with "because) I think Germany is a great nation. There are beautiful bulidings (all kinds of houses and churches) and kindly kind ("kind" is the adjective form of the word, since "people" is a noun. "Kindly" would be used to describe a verb) people. Germany is one of the most advanced inindustrial country countries (since you use the phrase "one of the most," it's implied that it's one of many. So, use the plural form instead of the singular form). Chinese China (You could also say "The Chinese") should study for Germany about the for its technology and the serious and strick (I'm not really sure what this is supposed to say). I like its big green fields. I heard that the country will be more beautiful because of the colors in autumn colors. I'm looking forward to visiting the country again in autumn.

Overall, great work! I mostly fixed small things (like making sure you're using the right preposition like "for" vs. "the" or "about," or parts of speech, etc.). Let me know if you have any questions!
