Let me look around, but I remember it being hard to find good price series for pork in China. Don't think the LH1 ticker is the one to look at, but maybe it's a reasonable proxy directionally...I'm not sure it's been a while since I charted the series against each other.
I'm looking at this for hog prices: https://tradingeconomics.com/commodity/lean-hogs - does this reflect the pork prices you are describing about?
