Hi Chiofang168 - How funny that I came upon your name. I was just here... on the Educator's PLN, and thought that I could look for someone with a similar name to mine. So... I typed in " C - H - I - O " just to see if anyone had a name like my name. And out of 9,000+ members... I found you! So, let me say welcome to the Educator's PLN! I see that you are on Mainland China...? Cool - that's great. I am currently taking more "teaching" courses and more "education" courses at a university with many Chinese grad students. We have had many laughs and are enjoying new friendship. I say welcome to you, and hope we can talk again.
