Ask Shandong dialect! ! !

2. "Duck egg" is said to be "Ya Dan"

3. "Duck" means "duck (son)"

As far as the nouns you provide are concerned, all parts of Shandong are basically pronounced in the above way, and there is not much difference. It's just that local dialects are different and sound different.

Some people also call eggs chickens, ducks, ducks and ducks, but they are rare. Not often.
