In the eyes of many foreigners, Chinese are the best hosts (主人) and the worst guests in the world. They’re not really bad guests, but because the guest-host relationship in China is much different than in some western counties, it appears they are not nice guests. And western guests sometimes look rude (粗鲁的) in the eyes of Chinese guests.

In China, guests are almost like gods. Whenever I enter a Chinese person’s home, there is always fruit on the table for me, and someone is quick to bring me a cup of tea or water. In the west, generally the guest is not a god. Acting according to the host’s way of doing things is usual behavior for a guest.

My wife’s mother, a very kind elderly Chinese lady, doesn’t smoke. When I see some of her guests smoking in her house, as a non-smoker, I feel unhappy. Usually I want to stop them directly, but I must realize that in China, to be a good host, she must not do that. In most North America homes, if you are a guest, and the hosts are not smokers, you should not smoke in their house. At the very least, you could ask, “Is it OK if I smoke?” “But, don’t be surprised if they say, “No, you can’t smoke.” In our culture, if you smoke in their home, you are a bad guest, but if they don’t allow you to smoke in their house, they are not a rude guest.

Guests in China also have special habits. Some western people may not adapt to these habits very soon. Thankfully my wife is Chinese, so whenever we visit a Chinese family she tells me to buy them a gift. However, giving a gift to a host is not always necessary in my country. So, if you invite international guests to your home, don’t be too surprised if they don’t bring you a gift.

In China, you probably won't need to change the guest-host relationship very much because you will probably only be the host, and Chinese are naturally very good hosts. If western hosts invite you to their house, try not to be too surprised if their style of treating you is not what you have expected.

Some days, don’t you think, "Wouldn’t it be nice if the laundry would just do itself?” Self-cleaning clothes may sound crazy. But Australian researchers have found a way to make something like this possible!

A team at RMIT University in Melbourne, Australia, found a way to put special nanostructures (纳米结构) into clothing, which can then clean the clothes. When sunlight hits the nanostructures,they break down the dirt and stains (污渍) that don’t belong on your clothes.

The nanostructures don’t break down the actual clothing because cotton and the other clothing materials are too strong to be broken down. According to CNN, the researchers cover the clothingin a solution made of silver and copper (铜) nanostructures. All it takes is 40 minutes of sunlight and your clothes will look as good as new.

So if you spill on yourself during lunch, you can step outside for a walk, and it will be cleanby the time you go inside. It not only makes your life easier, but it can also be good for the environment.

According to the US Department of Energy, the average load of laundry uses about 25 gallons (about 94 liters) of water. Water is a very important resource, so using less of it to wash clothesis better for the environment. But one of the scientists at RMIT University knows more needs to be done.

“There’s more work to do before we can start throwing out our washing machines,” said Dr Rajesh Ramanathan, “but this is a strong foundation .”

So what’s the next step? Ramanathan wants to either start selling the solution by itself or convincing clothing makers to treat the clothing with the solution while clothes are being made.
