Hey @chanya, and welcome to Steemit! Your introduction post is already a great start of your adventure on this platform. Post quality content, interact and connect with other people and I am sure you will see terrific growth.
You are always welcome to reach out to me should you have any questions. I have recently posted a guide on the MinnowSupportProject that could prove very useful for you - it helps beginners gain influence on Steemit with the help of experienced Steemers. Check it out if you'd like, and see you around! Cheers, @Finance2Nomad
P.S. I love Korea! I have lived in Seoul for a while. :-)
