China:
-(French voice without subs) playlist including:
A very recent web series called “If I were Pekingese” talking about censorship and many things about entertainment. Really interesting. It would be great if ppl could add subs in English so more ppl could discover it.

-English voice + subs: Wu Zeitian, The Empress Who Ruled The World (Chinese History Documentary) | Timeline

It’s the same empress we can watch in Detective Dee (the first movie of the series is available on Viki, but there are lot of other movies and dramas).
**Japan:**
- (French voice + Deutsch voice): “Le Japon vu du ciel / Le berceau des traditions” => “Japan seen from the sky / the cradle of traditions”

I watched this a few weeks ago, it’s really incredible how this country keeps its traditions (katana & paper crafters, geiko/maiko) + is modern at the same time.
The sentence I liked was: “If we believe we have talent, we are definitively mistaking.” (around 9:00) When we watch this documentary, we can’t help thinking that Japanese people are very humble and hard-working.
