Dear @goldgrifin007 !
It is essential to avoid the rancid oil in my canteen foods frequently so I try to avoid it as much as possible and this Ramadan, I will ultimately maintain the fresh foods and vegetables at any cost. And this marketplace will help me a lot o do that.
Yeah, the shop owners don't know English at all, but it is okay for me as I know very little conversational Chinese to buy things and other necessary conversational knowledge in Chinese.
Thanks for your attention.
