Hello @phuonganh2911le, welcome to the Steemit community! Glad to see another teenager on Steemit.
We have created a community for the teenage bloggers on Steemit named TOS where we help each other and interact with our peer steemians. If you are interested, you can contact me through Discord, @Chamu#2721
Good Luck!
Thanks you very much.
