Good news. Those who are interested to know where can buy good and nice Foo Chow Ang Zao also known as fermented rice residue can look for me. I understand by taking more of this during confinement is really good for health. Let me know I can pass you the contact number. Best, they are selling homemade Foo Chow Ang Zao believe to be so much better than those selling in Sheng Song. I've tasted both and indeed those from Sheng Song are not comparable in terms of taste and quality.
