Being a foreigner - golden rules

Hello mates
I have been traveling for most of my life.
I have started my journey since I was 5 with my father and around 14 started to travel by myself.

Now I am living China . I have lived in lots of places and I would like to share with you with some of my experiences so you can avoid some of my mistakes LOL I mostly contribute to the www.worldpolis.com you can find me there.

1. Before you go somewhere do some research - articles, friends any reliable sources.
I went to Africa I had a friend that gave me lots of info

2. Try to learn some of a frequent using words in a local language - thanks, please, beer
Chinese ?? ??

3 Make sure you keep your money safe and documents - it destroyed one of my trips to Spain when I couldn't leave Madrid for a long time.

4 Take your camera. I know it sounds weird but you can't remember most of the things after few years . I have this problem now i have been in so many places and I lost my photos shame
You can always post the on the websites so they don't disappear (worldpolis, facebook, anything you are using)

5 Be friendly but firm to the locals some of them are trying to use you.
First day in China I bought socks for 50 yuan and I could get them for 5 yuan . I was supposed to bargain but i didn't.

6 Don't look like a sitting duck!!! When you are in a new place always look as you new where you are going . Some people they just wait for a lost tourist to rob him.
I had in Slovakia . These people were following me and luckily I went into one of the restaurants and pretended to know one of the people there. Lucky me .

This is part 1
