Well, first of all, there is no "敢做敢当", it's a common misuse of "敢作敢当"; and second, this term is not exclusive for man; last, "敢作敢为" has nothing to do with "责任", which means do something in your own way without fearing to face any consequences, kinda like the spirit of "let the chips fall where they may" By the way, the "当"in “敢做敢当” means "taking responsibility". Got it?

In China, every place has its own special/characteristic food/cuisine.

you should write: The cultivative eggplant in the Northern and Southern Dynasties is circular, similar to the wild ones

yep, your way is wrong regarding the context, for when "地" is used in front of a verb, if is used as an adverb to describ the verb followed; so at this point, your sentence means "I started crying uncontrollably with difficulty", which obviously is way wrong from what you wanna deliver. I'm so happy I could dance can be: 我高兴得要跳舞了 I was so tired I fell over: 我累得摔了一跤 I was so upset I ran away can be said: 我很难过，所以走开了 BTW, likewise, u can't say 我难过得走开了, for that 得 is misused, and if u say so, ur audience would take it as "地" again, so the whole sentence will be ”I ran away with sadness“

Well, as a Chinese, I certainly know what you are talking about. As a matter of fact, what you are trying to tell is to roll one's tongue, based on which, the better way to explain it is "roll your tongue and try to blow out air" in my opinion.

我是东北人，但是我们也不这么说，尤其是“好容易≠好不容易”。我们倒是有时候会说，差点儿=差点儿没，比如“我差点儿（没）摔一跤!"

It really can has either meaning depending on the context; and apart from that, it can also mean "do you catch me" on some special occasions.

First things first, grammatically, there is no "to" before "somewhere" in both sentences. The first sentence can mean that the person you are talking about was on his way somewhere at the time; and the other one can mean that he had an intension or a plan to go somewhere and this action had not been taken yet. Is it clear?
