Tips Before You Travel to China

What should I do before travel to China?
1. Bring all the necessary documents you need to travel in China.
Don’t forget your passport with all necessary visas, and your international airline tickets.
2. Carry your passport with you at all times.
It’s required by Chinese law. Keep a photocopy on hand, too, in case the original gets lost. Or, upload a scan to a place you can access.
3. Arrive prepared in China.
Though there is shopping on every street corner, many of the things you may be used to may be unavailable to you in China. Bring toilet paper as most restrooms will not provide it. Plan ahead by saving leftover partial rolls of toilet paper, in advance of the trip. Each time you have a partial roll left, place this in a baggie and toss it into your suitcase. Six to eight small rolls will last a family of four through a two week trip. Five-star hotels will always have western-style toilets and toilet paper. Most larger airports will have at least one western toilet in the lavatory as well. Take only a key to your house or a car key with you. Leave all others at home.
•You need your own toilet paper, especially if you are traveling by train.
•These toilets are only available in the ‘country-side’, not in the metropolitan areas in China.
•You can buy toilet paper in China. It’s not expensive.
4. Bring Pepto Bismol and Immodium chewables.
Water quality in China is very poor and you may develop slight intestinal problems if you use tap water to brush your teeth, or if you eat vegetables which have not been cooked after having been rinsed in tap water. Chew two Pepto Bismol tablets before your meal to help prevent intestinal troubles.
•Again, only in the country-side places, not in the ‘metropolitan’ areas.
5. Bring any other medications you may need on your trip as well.
6. Bring clothes according to the season when you are traveling.
China gets hotand rainy in the summer, and very cold in the winter. Bring plenty of clothes, but remember you can always find a laundromat to get your clothes washed, or use the laundry service at your hotel. Beware, however, some laundry places use detergent that can irritate sensitive skin. Having your clothing dry-cleaned instead will avoid this problem.
7. Dress the part.
The standard dress for most places in China would best be described as “smart casual.” If your tour involves some formal occasions, bring along a formal suit or dress, too.
•China is somewhat like the USA. Summer in the south is very hot and humid, and winter in the north is cold and dry.
8. Be careful not to get any water in your mouth when you shower.
It tastes normal, but could easily make you sick. Always brush your teeth with bottled water.
•In small cities, bottled water that was filtered with cheap nylon filters is still being sold. Buy name brand bottled water in big supermarkets.
9. Consult your physician(s) or a travel clinic in advance of travel.
Your doctor or health-care provider will determine what vaccinations you will need, depending on factors such as your health and immunization history, areas of the country you will be visiting, and planned activities. Be sure to have your prescriptions filled before your trip. China requires that you present a letter from your doctor indicating the need for the use of any psychotropic medicines you might be taking. Bring antibiotics and any other prescriptions you will have to take during your travel. Count enough for your days of travel, plus a few spare pills. Bring all of this in the original prescription container. The Centers for Disease Control also keep an updated page on health information for travelers to China.
10. Write the contact information for each of your doctors on an index card.
Take this with you during your day trips in case you have a medical problem, and need to call home.
11. Stock a hip pack for each member of your party with a small roll of toilet paper, and a small bottle of hand sanitizer.
Non-alcohol hand sanitizer or wipes are best, as Chinese airport security will occasionally confiscate alcohol-based sanitizers (especially in Guangzhou). Enclose also a granola bar, some cough drops, and some gum, if you’d like. These will come in handy as you travel around town. Include a flashlight since electrical blackouts can happen at any time, and you might find yourself in a dark room.
• Remember that you are in China and not anywhere else! In bathrooms in China, to reduce the amount of waste used in the area there will most likely be no toilet paper so carry around lots of tissues. Tissues can also be found in local markets for only about 1-2 Yuan.
12. Take traveler’s checks, and some cash, as credit cards are not accepted by many restaurants and shops.
Bring a security pack or money belt which will allow you to keep any return flight or train tickets and your traveler’s checks, credit cards, and or cash, safely attached to your person, underneath your clothes. This way you can keep essential items safe if there is no safe in your hotel room.
• The major banks in big and medium size cities have ATM that accept foreign ATM debit cards.
•In small cities, some banks would not even exchange your USD for RMB.
13. Other things you may need: deodorant (cant be found even in big cities), raincoat and/or umbrella, hat, sunglasses & sunscreen (depending on the season and your destination), insect repellent, converter (power adapter) if you have one or if it’s necessary for you to have one. If you are a woman, bring your own feminine hygiene products.

iPhone 7 is Better than the Google Pixel?

Since the Google Pixel hasn’t been released yet the conclusions of this article are not definite. Also it takes into account prices which can also change. Anyways, here are three reasons why we think the iPhone 7 is your best smartphone bet (for now).
The first important point is durability. You’re bound to have an accident with your phone at some point and you absolutely want to purchase something that will last. The iPhone 7 tops the Pixel in this category. It meets the IP67 standards for splash, water and dust resistance. The iPhone 7 can actually be submerged in water and still works. Even though it’s tough Apple still recommend you use a case.

The second reason we prefer the iPhone 7 over the Pixel is design. Obviously this is a personal preference, and both devices do look similar. Nevertheless there are some differences that have been noted which give the iPhone an edge. According to the majority of reviewers the iPhone 7 is extremely comfortable to hold; featuring wonderfully curved sides and corners. The Pixel, while comfortable, just doesn’t match the iPhone on this point. Furthermore, Apple has done a better job blending the antenna breaks and decluttered in the phone’s rear panel. Finally, in our opinion, the iPhone 7 just looks better.

The final reason is the price and availability. Both phones are expensive, so if you’re tight on money look for a cheaper alternative. The base cost for both phones’ 32GB and 128GB models are $650 and $750. The 256GB iPhone is $850. Unlike the Pixel which is a Verizon exclusive in the US, the iPhone is available with multiple carriers. This means greater flexibility on payment plans. Furthermore, the iPhone is available in more countries and from more retailers. To summarize the iPhone is more widely available, has more service carriers and a more flexible payment plan.

Of course, there are many other factors involved and it is up to the buyer to decide what characteristics in a phone are the most important for them. The Pixel’s battery and audio seem to beat the iPhone according to most online reviews. If these are two qualities you really care about then go for the Pixel; and be sure to enjoy the high quality audio with one of our In-ear Genuine Wooden Earphones. If you’re still going with the iPhone despite the poorer performing battery stay charged using one of our certified Apple MFI lightning cables.
The other important product characteristics such as display, software, functionality and camera generally tie in most online reviews with neither the Pixel or iPhone beating out the other. However, it’s still early and further testing might show clear differences in these areas.
