Darkest Sword / The Great Duel (1970) HK release dates

[Chen Hung Lieh]

While sniffing around a little on that HK newspaper digital archive, I came across with newspaper ads of Great Duel and the Darkest Sword.

Great Duel:
I changed the release date 07/31/1970 from HK to Taiwan, because I couldn't find a HK newspaper ad for that day. IMDB agrees with that. But I found HK ads for a threatrical run from 11/19/1970 to 11/25/1970. IMDB agrees with that again.
See Page 20 and page 16

Darkest Sword:
I changed the year from 1971 to 1970, as I found HK ads for a threatrical run from 11/12/1970 - 11/19/1970.

many of the taiwan (and china) release have an hk date, but most are wrong, its because before we didnt have specified country release so now we need to change them but me i know nothing about these movies so i won't touch them, maybe some are really HK release date but i suspect we can change near all to taiwan without problems, also, they're probably a lot of copy and paste from others (wrong?) sites, me i will not search old newspapers to find real release date hahaha no time for that but if anyone want to try why not, its a great idea !! thank you for your great works so far
