Taiwan Province: Mandarin, but with their accent.
Hong Kong: It's more Cantonese, and some words may not be understood by people who speak Mandarin.
Japanese: It's all Japanese. Is the Japanese edition suitable for decoration? For people who don't understand Japanese.
Actually, I don't think the quality will be too bad.
Personally, I like to buy more Taiwan Province version, because the price is relatively cheap, NT$ 80 ~ 90 and RMB 20 ~ 22 will do.
Hong Kong version of HK28, most of the prices are around 28 yuan.
Japanese edition is definitely more expensive, around 50 yuan. (But it's cheaper in Japan. )
I guess I'm 26 or 27.
Because on April 22nd, Japan paid 25,
