My hobbies

I love reading novels during my leisure time. I used to crouch curl up on the couch, reading novels with a cup of milk tea in the afternoon and enjoying the warm sunshine shedding shining in the room. Besides Additionally, I am so in love with dancing. I feel positive and energetic when I dance. I learn to express my emotion through dancing, to challenge my limits by practicing and practicing. Though exhausting, the happiness and accomplishment dancing brings me is indescribable. Traveling is another way I get refilled. Since I was a child, my father has taken us to traveling every summer and winter vacation. Because my family is not particularly wealthy, going abroad is an extravagant thing for us. But, we deeply experience the endless natural beauty of Formosa, our beloved country, Taiwan. Tai-Tung is the place we go most often; the spontaneous lifestyle is totally different from that in the western cities. The mountain(s?), the sea, the enthusiastic people and the hot spring(s?), everything here is so relaxing and beautiful.

Nice work! Your grammar is excellent, and you are making a huge effort to use some beautiful English words. Bravo! Unfortunately, sometimes the word you are choosing is not *quite* the word you are looking for. A few clarifications:

-"Crouching" is a position that is ready for action. For instance, you could say a ninja is crouched and waiting to attack, or a cat crouches in the grass waiting for a bird. "Curl up on the couch" is a common phrase that means to make yourself cozy on the couch, often used when talking about reading.

-When you use "shed" with the word "light," it is in the phrase "He shed light on this subject," which is an idiom that means that he made the subject easier to understand.

-When you use "besides" as a transition word, it is usually in the context of making an excuse. For instance, if you told someone, "I am going to spend all day reading this book. I've been wanting to read it for a while, and besides, school is cancelled so I have the time." To move to the second topic in a list (as in what you wrote), you can use "also," "additionally," "moreover," "in addition," and many other options.

-"Exhausted"--> describes how you feel, i.e. "I am exhausted from dancing so much."  "Exhausting"--> describes the activity that makes you tired, i.e. "Dancing is so exhausting."

-"Comfortable-off" -- I have not heard this phrase before. There is "well-off," which generally follows a linking verb ("We are well-off") but is not usually used as an adjective in front of a noun ("We are a well-off family"). To me, the word "comfortable" would imply that you do have plenty of money, which is not what I think you meant, based on the rest of your sentence.
