I know they're not strictly CHinese version but itll give you a rough idea:
Curry sauce, ambient, 100g 5½
Curry sauce, fish & chip shop, average portion, 150g serving 6
Fish & Chip Shops, Curry Sauce, average portion, per serving 6
100g is like a very small pot of yoghurt size.
Like vintagepockets says, boiled rice or boiled noodles are free but once you fry anything it goes off the scale
