Merge? 于虹 Yue Hung & 于娘 Yue Leung

[heinz Germany]

The Mysterious 于虹 Yue Hung (Baboon belle) https://hkmdb.com/db/people/view.mhtml? ... ay_set=eng is listed in Bloody Mask (1969) (no role name), but no clue why and where the credit comes from, but still we have another "rare" young actress
于娘 Yue Leung https://hkmdb.com/db/people/view.mhtml? ... ay_set=eng. The same person with different stage name?
