Cast in Yellow Muffler (1971)

[heinz Germany]

we list in the cast: Yueh Hua...Dancer, Lily Ho Li-Li, Cheng Pei-Pei & Chin Ping as Singer, yet the huge castpage does not
provide any portrait of them. Was this Hong Kong Nocturne (1967) footage (Same director?), since by that time Chen Ping already retired after shooting of 'The Price of Love' (1970)
