Road Names

Main roads, avenues are often divided into different sections based on the four cardinal points.  For example, Zhongyang Lu (Zhongyang Road) may be divided into Zhongyang Dong Lu (Zhongyang East Road) and Zhongyang Xi Lu (Zhongyang West Road) .  Similarly, you will probably meet Zhongyang Bei Lu (north road) and Zhongyang Nan Lu (south road).  In large cities such as Shanghai and Beijing, Road names also display the pinyin translation with Chinese.

Bargaining

In our opinion, the bargaining is essential in China, especially for English speaker.  Sometime, you may be overcharged several times of original price.  Therefore, travelers should be very careful when shopping in markets or anywhere else where prices are not indicated.  We intensively suggest you to bargain and firmly state your price and just walk away if the one doesn't agree.  Shopkeepers often agree once they realize they're losing a potential sale.

Tipping

Tipping is not expected in China, Hong Kong and Macau.  Some restaurants include a service charge on the bill.
