Hello @dzungmrf!

I noticed you have posted many times since you began your journey on Steemit. That is great! We love active partipants.

I do want to point out that the Introduceyourself tag is meant to be used once only to introduce yourself to the Steemit community. You have now posted 19 times using the introduceyourself tag. Please see this link for more information Tag Spam?

Please take this into consideration and help build a great platform!
