Finally found a street with some Chinese shops today!
A co-student told me where to find them, in the station area.
So I walked there and found 2 shops, one with live fish and fresh veggies and meat and the other more “supermarket”-like with different kinds of chillies, dried, sauce, even sambal and finally real soy sauce!
Chicken with lots and lots of chillies tonight for dinner with noodles, yummie!
