米大，天然气looks like a falling knife now. Should we catch it based

on your recommendation? I still remember the old saying of the wall street:

don\'t catch the falling knife. Even this knife has been falling for a while and shouldn\'t have too much steam. I am still afraid of getting hurt.

I also remember the other old sayings: like:

follow the trend not against it, etc. As nocufusion said cheap can get cheaper. Should we wait until the trend is up, say, when sd passes the 200ma?
