Extended answer:
(1) Vietnam:
Vietnam is located in the east of Indochina Peninsula, bordering China, Guangxi and Yunnan in the north, with a boundary line of 1.347 km. West borders Laos and Cambodia; East and south face the sea.
Vietnam has a tropical monsoon climate with a land area of 329,000 square kilometers and a population of 92.7 million (20 16). It is divided into eight regions, namely: Red River Plain, Northeast, Northwest, North-central Region, South-Central Coastal Region, Xiyuan, South-East Region and Jiulong River Plain.
There are attractions such as Ho Chi Minh Mausoleum, Bating Square, President's House, Ho Chi Minh's former residence, Huanke Lake, West Lake, Duzhu Temple, Confucian Temple, Medical Temple, Yushan Temple, Zhenwu Temple, Zhenguo Temple and Jinlian Temple.
Vietnam is a multi-ethnic country with 54 ethnic groups, with Jing ethnic group (also called Yue ethnic group) as the main ethnic group, accounting for more than 80% of the total population.
Located in the middle of the Red River Plain, Hanoi is the capital of Vietnam and the national political, cultural and scientific center. Ho Chi Minh City is the largest port city and economic center in Vietnam, consisting of Saigon, Di 'an and Jiading.
(2) Travel considerations:
1. power adapter: not required.
2. Cash: Eating, drinking and having fun, Vietnamese dong is more common. It is more cost-effective to withdraw cash with a bank card free of daily handling fee than to exchange it 1/3 or so.
3. Mobile phone card: Generally, only traffic is used. The flow card can open the international roaming of domestic operators, and WiFi can be seen everywhere in public places in Vietnam. You can also buy a flow card from a Vietnamese telecom operator.
In Ho Chi Minh, we bought a 6.6 GB flow card, valid for 30 days, in 45 yuan. By the time they left on the ninth day, most people only used less than 1 GB, which shows how convenient WiFi is. It is suggested that after going to Vietnam, find a store that sells mobile phone cards to buy cards and solve the problem on the spot.
4. Air tickets: Most people travel to Ho Chi Minh City and then go to Minai or Nha Trang. On the way back, take the 10 hour night bus from Nha Trang to Ho Chi Minh, and then fly back to China. The night bus is very tired. If you can buy a direct flight ticket to Nha Trang, don't pass by Ho Chi Minh. It's a waste of time and tiring.
5. Transportation: There is no subway in China, and public transportation is underdeveloped. It's safe and friendly to take a taxi downtown and hit Green Merrill Lynch without jumping the price. The traffic between the two cities depends on buses, and big companies include Xinguang Tourism and Fengtai. Basically, when you arrive in a city, you can buy a ticket and leave a few days later, so you don't have to buy it too long in advance. There are many tourists from China in New Coffee. The front desk of the hotel asked me why people in China want to drink new coffee ....................................................................................................................................................
6. Eat and drink: Eating and drinking casually is basically not expensive. But to be honest, there is nothing delicious except coffee, red wine and tea ... tea is particularly delicious, hmm.
7. Language: Nha Trang has a developed tourism industry, and most people speak English very well. Some shops even have employees who can speak Chinese. When you meet a vendor who doesn't know English, you can also directly open the calculator and let him enter the price to complete a pleasant business.
