For instance Hebei should have won easy today if we take away "home advantage". They are much better team IMHO.
They definitely are, thats why I picked them. They were 3.0+ when odds came out and 2.30-ish before kick-off, so initial prices were wrong. Hebei has better foreign players and better chinese players, but thats not always enough in football
Shijazhuang is doing pretty good, they have good team chemistry, players are in sync and they still live from the promotion hype a bit. But at some point they will start to fade and lose more games. You can compensate lack of quality only for so long. I guess it must be an anomaly but check stats a bit. They are definitely slanted in favor of "home" teams.
I didn't notice thus far, because I disregard home/away in CSL for the moment completely (makes no sense when in a bubble^^). But a quick glance at the stats shows Group A doing poor at "home" and being strong in "away" games in general. It's the complete opposite for Group B. Maybe you found a pattern here
