Welcome to steemit Hive account@honghkd :) I was a high school English and ESL teacher in Canada for many years, so I totally get what you're saying about math haha

Your art is beautiful! Here's a tip: for posts to be recognized as your own work, when you show photos of your art, include process photos too ... that way it "proves" that you did it :)

I found your post because Hive account@macoolette featured you in her Pay It Forward Curation contest entry; we'd love to have you join us with a post of your own next week ... it's a great way to start developing your own community here too :)
