I grew up in a very ethnically diverse area, so everyday I would here greeting, and farewells in Spanish, Italian, Ukrainian, Polish, etc. So, without knowing it I developed and ear for speaking languages. I have studying Spanish, French, Cantonese, Vietnamese and a few other languages. However, the only language I really enjoy studying is Chinese Mandarin, a language I never came in contact with when I was a kid.

I just learn one(English). Because I live in an English speaking country. I learned through scatch mostly watching youtube videos. like <yt-formatted-string id="owner-name" class="style-scope ytd-video-owner-renderer" style="--yt-endpoint-hover-color:var(--yt-channel-owner); font-size: 1.4rem; line-height: 1.6rem; color: rgb(0, 0, 0); font-family: Roboto, Arial, sans-serif;"><a class="yt-simple-endpoint style-scope yt-formatted-string" href="https://www.youtube.com/channel/UCxiTJyV8NhkKQbzlzG3Ak_w" style="display: inline-block; color: var(--yt-endpoint-hover-color, var(--yt-endpoint-color)); font-size: var(--yt-formatted-string-endpoint_-_font-size); font-weight: var(--yt-formatted-string-endpoint_-_font-weight); line-height: var(--yt-formatted-string-endpoint_-_line-height);">TeacherPhilEnglish</a>. learn English lesson 1-50. </yt-formatted-string>Learn American Accent English Lesson #50 etc. I also use Anki app to memorize new words. sometimes I rewrite an entry on notebook session. when I take a train, I will use Anki to review it. I have read kindle ebook and have watched netflix TV shows. they consolidate my knowledge.  Also, I do language exchange too. but I can't find the right one at the right time yet. new to use speaky and hellotalk. they seem to fool me. I always roam anyway.
