Please correct my English

Hi! My name is Helin and I'm Chinese. I was born in China and got an education there. However, my grandparents are korean but they migrated to China when they were young. And they teached me the Korean language , that's why I can speak Chinese and Korean as well. So, I love k-pop a lot, and my favorite singer is CNBLUE. Besides that, I studied abroad in Japan 2 years ago and majored in accounts. Now I‘m working in an International trading company in China. Athough almost all of my customers are Japanese, I still need to use English, so I should improve my English comunication and writing skills. So, if you are native English speakers and have an interest in korean and Japanese and chinese language, please contact me. I'm waiting for you in italki.
