Thanks, erdong!

It is not an easy dicision to upload articles here.
FengYuan is a great place that I really enjoy a lot and learn a lot. There are so many talented people here. I love to stay behind and see all of you fun conversations.
That's the reason I like to support it. But with my knowledge and skill, it is impossible to get something impressive. To upload it or not, it is a hard decision. Just for support purpose, I did it. I'm happy to see all of you comments. But don't bother to put it on top. I'm sure more and more high quality posts will show up, with all of you encouragement. Thank you!!!
