Welcome @joyulin2010 Joyu you're cute! Thanks for introducing yourself to us. Your english is good, I can understand you and that is what matter. For me English is like lingua franca for us global human right now and to use perfect english to communicate is not necessary but we do want to improve our english too, so just do it 😅 english is my second language too, most of us here on steemit I guess.. only small numbers of english native speakers here.
