Korean Culture: Soup and Outdoor Sports For In Doors

So I am Chinese American and have grown up with Chinese food my whole life. I like some of our soups specifically Ox Tail or Chicken Soup. Now I want to point out that my exposure to Korean culture is KTown Los Angeles.

So you guys understand where I am coming from. So I go to these nice popular soup places in KTown right? And I can kinda split the soups into two category. There is the flavorful spicy soups which I love and understand. But then there are some Ox Tail and Chicken soups which are just bland as fuck. I mean I kinda get it, because the purpose is for you to add how much spices and salt to the soup to suit your flavor. And that's my question. Why? For most soups I've had, whether it is Chinese chicken soup, Vietnamese Ox Tail Soup, or Mexican Pozole, once the dish is done, it comes with a lot of flavors. You can add stuff if you like, but generally no. So it was odd to me that when I got my chicken soup from a korean restaurant, that it tasted very bland without me adding salt or spices to it. No matter what korean soup place I go to, it's like that. So I am curious as to why that is and the philosophy behind that. Is it just simply so that people can flavor it to their own taste or is there something more.

My second question is regarding outdoor sports, but indoors. This may or may not be a korean thing. So the reason this comes up is because KTown has a indoor range that lets you practice your swings. Not the kiddy indoor putt putts, but more actual golf like. It's called the Aroma Golf Range. I know that there is a new place that is also like that but for baseball called StrikeZone that will open soon. Maybe it's just me not being as worldly as I should be or I don't go out to other places enough, but until told otherwise, right now it seems like a very korean thing to me. So is it? And if so, why and what is the philosophy behind that?
