Tigress is Coming (1967/68) release date

[Chen Hung Lieh]

Does anyone have information of the 1967 release date?

I doubt this 1967 date, but will not change it as long as I don't know on what the year is based on. The only concrete release dates I can find are from 1968 and 1969, the movie was originally added with the year 1968, then someone changed it to 1967 (according internet archive, I have no access to the edit history, so I can't ask the responsible editor), so there must have been a reason.

Changing release years to earlier ones is a safe thing when there's some proof, but changing them to later ones always feels like I might not be aware of some important facts. I already did a mistake of this kind where I had to change back my own change after finally finding a 1969 release date of Son of the Swordsman, I'm determined to not repeat this kind of error.
