Haha, I only used it for travel advice (buses, trains etc.), city maps and basic info on cities - On their advice I took a boatride from Siem Reap to Battambang an it was $#@!ing horrible so i decided to ignore all of their advice from then on

. The book on china is helpful though - the glossary of Mandarin - Pinyin - English was really helpful, especially in the first few days until i got my head around the language.
