The local mosque has a halal restaurant nearby with this sign:
Qīngzhēn huíhui jiǎozi yáng tāng guǎn
I translate this approximately to "halal ethnic Hui dumplings and sheep soup restaurant". (Google Translate gives: "Halal back to dumplings sheep soup hall".)
Ordinarily, I would expect to see 羊肉汤 (yángròu tāng) = "mutton soup", but the sign says 羊汤 (yáng tāng) = "sheep soup" which surprises me.
Question: Is 羊汤 an alternative word for 羊肉汤?
