These two appear to be the same person. (1) appears as an actress in two films for which (2) was the costume designer, and in (2)'s only acting appearance, The Loot, the same name is also credited as the costume assistant. We could also change her name to Lu Hsiao-Hung after the merge, seeing as she worked in the Taiwanese film industry.

If nobody stops me in 15 days I will merge them.
