I don't know the size of your dumplings. If ten glutinous rice balls the size of a wine-brewed dumpling are only about 2,30 grams, because they are really too small. And one dumpling wrapped in my home may cost 2,30 grams, so ten dumplings can look like about 200 to 300 grams. If you go to tsat po street to eat dumplings there, you may get 40 or 50 grams for one, and 4500 grams for ten, which is about a kilo.
