Chow Pked, oil is messy. 135 inefficient now, so 857 can get it cheaper.
2688 put in lose money assets, if it is bad, main shareholder win, if it is good, it also adding in low price, also win.
Both company main shareholder play all.
Actually 135 seems doing fine except LNG and Oil Mining.
2688 no follow, but just suddenly become from one of the most high PE large cap to lowest large Cap natural gas stock(forward 14pe)
