It's Been So Long Since I Spoke English-

I studied English for 12 years when I was a student. I stopped studying English <s>for</s> 10 years ago. Now, I'm trying to brush up on my English. Then, what am I supposed to do?* Obviously, I need to read the books and newspapers which <s>is</s> are written in English. Thankfully, I found the Italki online studying language platform, I like to study here with other foreigners. It's Sunday afternoon, our family is relaxed at home and I'm logging <s>in the</s> on Italki <s>for practicing</s> to practice my English again! I really like Italki. I'm reading some English picture books for myself.** Also, I'm finding some booth design samples for my exhibition booth. <s>It is</s> I am so happy to have my own time at home. Because of <s>the</s> Covid-19, I cannot hang out with my family <s>in</s> outdoors. Listening to the English radio and working <s>at</s> in my room are quite better than I thought.

* This is pretty colloquial. Another way you could express this is "What am I supposed to do then?"

** While "for myself" will be well understood by any reader, the wording feels slightly awkward. 예를 들면, 내가때문에 영어책을 읽고 있어요. <- doesn't make too much sense. You can change it to "I'm reading some English picture books to practice English." 영어를 배우기때문에 영어책을 읽고 있어요.

Comments <s>of</s> on videos*

I thought the symbol of Okinawa is simply tropical scenery, beach and blue sea, just like <s>Hawaii islands</s> the Hawaiian Islands. But** after I saw these videos, I found that the most special thing about Okinawa is the fusion of traditional Japanese culture and tropical island style. In the video, there was not only island scenery, but also the Japanese festival, the fireworks in summer and so on.***

Because of the special location, climate and life style***, the native people <s>in</s> of Okinawa seem<s>s</s> to be open, optimistic and enthusiastic***. The people <s>People</s> in the videos smile<s>s</s>**** brightly and they get together to celebrate their festivals. <s>Both</s> Men, women and children all seem to like to participate in activities, and the relationships between people <s>is</s> are also very close.*****

And****** I think they may have a deep sense of identity with their culture. As a special part of Japanese culture, they protect their unique culture very well.******* The people in Okinawa are proud of their culture, and hometown consciousness is very strong.

Okinawa people have some Japanese characteristics, but there are also some differences. Like normal Japanese citizens, they attach great importance to traditional festivals and the bonds between people. They are polite and conservative. At the same time, they are more enthusiastic and open.

* Titles should be Capitalized. Also I believe you are talking about your personal comments/thoughts on the videos you have watched. Using "comments of videos" suggests that it is the comments found in the comments section of the videos. You might also want to add more context to the title such as "My Comments on the Videos I Have Watched" or replace comments with "My Thoughts on the Videos I Have Watched"

** In grade school I was taught to avoid beginning sentences with "But" (however that might not be true). Regardless you can change the "But" to "However," if you would like.

*** (Personal preference) You can add the oxford comma (..the Japanese festival, the fireworks in summer, and so on.)

**** Since the subject is a plural (The people), you need to conjugate the verb (smiles -> smiles)

***** Since you have three subjects (Men, women, and children), using "Both" (a counter for two objects) should not be used. I added "all" to emphasis the importance of the entire group being involved (as you were trying to do with "Both")

****** Same thing as beginning a sentence with "But". You can use "Furthermore," if you would like but the word choice is up to you.

******* The prepositional phrase "As a special part of Japanese culture," is followed by the subject that it is modifying. I believe that you are trying to say that the people of Okinawa are what is special about Japanese culture, but then continue to say that they are protecting the unique culture that you previous described them as. While this is not incorrect, it made me reread that sentence and you can choose to reword this if you would like. (As a special part of Japanese culture, the people of Okinawa put great effort in protecting this way of living.) <- is an example but I do not wish to change the spirit of your writing.
