Recently, I heard this over the radio.
There was once a lady who has to bring up 9 children. Her husband passed away when the 2nd last baby was only 2 year old.
They stayed in China Town, Duofu St.
The mother scooped up rice fallen from lorry together with egg of cockroach and rat dropping.
She cooked them altogether and told the children they were black rice. She could not wash as after washing, nothing would be left behind.
Sigh... now we can see a lot of food waste when we dine at food court!
