Actually the goyslopified stuff is/was also very sus.
My maternal grandparents actually refused to buy me takeout or take me restaurants when I was staying in China with them during the summers all those years ago. The only exceptions were a few restaurants where my grandparents had known the owners for a long time and knew their moral character. My grandfather is the one who started my interest in cooking but my mother was the one who taught me most of the recipes I know, which are actually just my grandfather's recipes.
If you believe gutter oil to be bad, then get ready to never want to eat Chinese cuisine (from CCP land) again. Taiwan is fine as health and safety is much stricter but I'd personally go to Singapore/Malaysia for Chinese cuisine.
