Hi all, could anyone help me out with finding some of my childhood Asian food spots?

Specifically, are there any large filipino stores or asian stores in general that sell duck, roast pork, pig ears, steamed buns, shumai, etc. in or around Chinatown, specifically to go and usually in white or clear plastic containers? Or any spots that sold prepared filipino foods like ensaymada, hopia, pandesal, suman, etc.

A lot of stores away from NYC and even in CT bring this food from New York and sell it in their own mom n pop small asian marts. This food is my childhood and since the White Plains mall closed, we aren't sure where to buy this food anymore, but don't know where these Asian marts get this food either. They seem like the same source(s) too, since the recipe, containers and quality are consistently the same, but feel free to correct me!

I'm essentially looking for the source of where several Asian marts are getting the duck, roast pork, buns, filipino food, etc. from. If you aren't sure, I'll also take recommendations for spots with these foods!

Thanks for any help!
