I'm wondering if anybody has any favorites set in the 1920s?  I have a list of about 50 Republic Era dramas, but they cover a fifty year span, and I'm wanting the 1920's feel.

I've watched two dramas which correspond to your research... I didn't really like it but I know how much people like it sooo I think it is just my cup of tea. So I recommend you both of them because it fulfills your requirements and they are pretty much liked by everyone lol

- Arsenal Military Academy (beginning of 20th century)

- Rookie Agent Rouge (1937). 

Soon, I will watch My Roommate is a Detective (mid-1920's). It's famous and well-appreciated so I think that's what you're looking for!

Thanks! Yeah, I started looking at this genre again since I'm watching Hu Yitian's Appledog and DT drama.

Yeah, you can find Hu Yitian as the male lead in My Roommate is a Detective! 

I guess you've already watched Go Go Squid if you're currently watching DT Appledog, if it isn't the case I highly recommend it even if it's not during the Chinese Republican Era lol

Cho Na, Shenmi, thank you!

The Bund - It's set in the 1920s.
