It just isn't natural for us to speak in Mandarin at home. So Oliver's and Heidi's exposure to Chinese and dialects are quite limited.
In the past he would slang his "xia yu" (raining) and "niu nai" (milk). He don't say them anymore, instead he has now a funny accent on his name (zhou yi en), and "wu ming tao".
He also doesn't quite like us to call him by his Chinese name, insisting it should be Orriverr...
