Are you carrying too much on your back at school? I’m sure lots of children of your age will say “Yes”. Not only the students in China have this problem, but children in the United States also have heavy school bags.

Doctors are starting to worry that younger and younger students are having back and neck problems as a result of school bags being too heavy for them.

“It’s hard for me to go upstairs with my bag because it’s so heavy,” said Rick Hammond, an 11-year-old student in the US.

Rick is among students who have common school bags with two straps(带子)to carry them, but many other students choose rolling(有滚轮的)bags.

But even with rolling bags, getting up stairs and buses is still a problem for children. Many of them have hurt their backs and necks because of the heavy school bags.

But how much is too much? Doctors say students should carry no more than 10% to 15% of their own body weight(重量).

Scott Batch, a back doctor, said children under Grade 4 should stay with 10%. But it is also important that older children don’t stay with over 15%, because their bodies are still growing.

“Children are losing their balance(平衡)and falling down with their school bags,” he said.

Parents and teachers are starting to tell children to only take home library books they will be reading that night. Some teachers are using pieces of paper or thin workbooks for students to take home.

One of the best answers is, as some children said, to have no homework at all!

The porter brings your bags to your room and helpfully explains all you want to know. Then he points to the phone and says: “If there's anything else you need, just call.” All this time you have been thinking one thing: “How much should I tip(付小费)him?” To make your next trip a little easier, here's a guide to tipping across some Asian countries.

Bangkok

In general, the more Westernized the place is, the more likely you will be expected to leave a tip. Some top-end restaurants will add a 10% service charge to the bill. If not, waiters will appreciate you tacking on(附加)the 10% yourself. However, if you're eating at a lower-end(低档的)restaurant a tip is not necessary. If you're staying at one of Bangkok's many five-star hotels, expect to tip the porter 20 to 50 baht(泰国货币单位), depending on how many bags you have. Taxis are now metered in Bangkok. Local custom is to round the fare(车费)up to the nearest five baht.

Hong Kong

Tipping is customary in this money-mad metropolis(大都市). Most restaurants add a 10% service charge to the bill, but the extra money often ends up in the pocket of the owner. If the service is good, add another 10% to the bill, up to HK $100 in an especially nice restaurant. For HK $10 hotel porters should do it at all but the nicest hotels where a new HK $20 bill may be more acceptable. When in a taxi, round up(凑整数)to the nearest dollar.

Kuala Lumpur

Tipping in Malaysia is limited to the expensive Westernized hotels, which often add a 10% service charge to your meal or hotel room. If you are at a hotel restaurant, expect a 10% service charge. But at local restaurants, there's no need to add a tip. At five-star hotels, one or two ringgit(马来西亚货币单位)will content a porter. At lower-end buildings don't feel you have to tip. Like Bangkok, many taxis are now metered so you can just round up to the nearest ringgit.

Seoul

Tipping is not part of Korean culture, although it has become a matter of course in international hotels where a 10% service charge is often added. If you're at a Korean barbecue joint(烧烤处), there's no need to add anything extra. But a nice Italian restaurant may require a 10% contribution. If you're at a top-end hotel, so expect to pay 500-1 000 won per bag. Taxi drivers don't accept a tip. Keep the change for yourself.
