One bag, that’s it.

The importance of packing light cannot be overemphasized(过度强调). Limit yourself to 20 pounds in a carry-on bag. A 9’× 22’ ×14’ bag fits under most airplane seats. And after you enjoy that sweet mobility and freedom, you’ll never go any other way.
You’ll walk with your luggage(行李) more than you think you will. Before leaving home, give yourself a test. Pack up completely, and practice being a tourist for an hour. Fully loaded, you should enjoy window-shopping. If you can’t, go home and thin things out.
Packing light isn’t just about the trip over and back—it’s about your traveling lifestyle. Too much luggage marks you as a typical tourist. It slams the back door shut. Changing locations becomes an important operation. With only one bag, you’re mobile and in control. Take this piece of advice seriously. Pack light, and pack smart. These days, you can’t bring anything possibly dangerous—such as knives, lighters or large amounts of liquid (液体)—in your bag.
What to bring?
How do you fit a whole trip’s worth of luggage into a small backpack or suitcase(衣箱)? The answer is simple: bring very little.
Bring out everything you think you might need on the floor. Pick up one item(件) at a time and check it. Ask yourself—not “Will I use it?”, but—“Will I use it enough to feel good about carrying it all the way? The world is getting really small—you can buy Colgate toothpaste, Nivea cream and Gillette razors in almost every country.
Think about what you can do without—not what will be convenient on your trip. When in doubt, leave it out.
