When purchasing video software such as DVD, BD or VCD, take note of both the broadcasting system and the region code. The broadcasting system in Japan is NTSC and China is PAL. To play PAL in Japan, a PAL compatible video player and TV, or a video player that can convert PAL into NTSC is required (BD is compatible with both). The DVD region code for China is 6 and Japan is 2, and the BD code for China is C and Japan is A (does not apply to VCD). Although the code for the video software and video player must match in order to be played, it can still be played if either is all-region compatible.

The color of the postal service in China is dark green, so the mailboxes are in dark green, not red. For airmails to Japan, postcards are 5 yuan and sealed letters are 5 yuan (up to 20g) and above. Business is divided into postal business and telecommunications business in China, and most cities have separate postal bureaus (postal services and telegraphs) and telecommunication offices.

The official language of China is Standard Chinese, a language that was created based on the Beijing dialect of Mandarin which is spoken by China's most dominant majority ethnic group, the Han race. Different ethnic groups have their own official languages. Additionally, even Mandarin which is spoken by multiple ethnic groups is divided into the Northern dialect, Wu (around Shanghai), Min, Yue and Hakka dialects as a result of the large territory of China. Each of these dialects differs so greatly that speakers of differing dialects cannot converse with each other. English is often not understood on the streets.
