There is no way to say how much you need. It depends on your itinerary and whether you have bought anything. The train fare is about 2000, and the plane is 3000+. That depends on your spending in Tibet. The sun in Tibet is very strong, so it is recommended to bring sunscreen and sunglasses. Don't catch a cold during your stay in Tibet, and take all the medicines. Because altitude sickness affects appetite, bring some high-calorie chocolate; If you want to go to a place with high altitude, such as Namco, you'd better take a thick down jacket. Even in August, it will freeze at night with low temperature. Temples are the most important cultural tourist attractions in Tibet. According to the custom of Tibetan Buddhism, worshipping Buddha must go clockwise. It is worth noting that in some temples of Bonism (the primitive religion of Tibet), the direction of turning meridian is just the opposite, and it should be counterclockwise. Visitors should choose a good diet before preparing to visit the temple, and it is best not to eat garlic. "Even if the temple is on fire, don't let people who eat garlic enter the temple." This proverb expresses a religious custom. Visitors had better take off their hats before entering the Buddhist temple. Don't make noise, touch the Buddha statue or litter in the Buddhist temple. You are not allowed to make videos or take photos in Buddhist temples without permission. Many temples in Tibet have dogs. Please don't drive them away loudly or hit them with something. There is a Tibetan proverb: don't hit the dog in the temple, it will break the Lama's heart. In addition, many Tibetan elders will follow some sheep with red silk hanging behind them when they turn over the scriptures. These sheep are called "herding sheep" and should not be disturbed. Don't touch the heads of Tibetans. Sticking out your tongue is an act of humility and respect for each other. Put your hands together to express your blessing to the guests, but pay attention to the fact that Tibetans are most afraid of others touching their heads. Offering Hada is the most common and grand etiquette for Tibetans. When the hospitable host presents Hada to the guests, the guests should bow and accept it. When entering the homes of ordinary Tibetans, generally do not step on the threshold with your feet; When addressing a person's name, "la" is usually added after the name to show respect for the other person. When sitting, you can sit cross-legged, don't straighten your legs, and point your feet at people. When accepting gifts, you should pick them up with both hands. Proper preparation of commonly used drugs for "altitude sickness" Many Tibetan tourists are very worried about "altitude sickness" while longing for the mysterious trip to Tibet. For such concerns, Professor Cen Weijun, director of the Institute of Cardiovascular Diseases of Tibet Plateau Disease, suggested that visitors to Tibet must scientifically understand and treat "altitude sickness". According to Cen Wei Jun, at an altitude of more than 3,000 meters, human hypoxic diseases caused by altitude hypoxia are collectively referred to as "altitude sickness". Experts pointed out that colds, high fever and excessive fatigue are all inducing factors of altitude sickness. How do tourists cope with altitude sickness? Cen Weijun suggested that tourists should have a good rest and not do strenuous exercise a few days before entering Tibet. After reaching the plateau, it is best not to lift heavy objects or run. Be sure to rest on the day you enter Tibet, and try to avoid receiving visitors, banquets, visits and other outdoor activities. In addition, experts advise tourists to prepare some commonly used drugs according to their own conditions before entering Tibet, such as anti-altitude sickness drugs, anti-motion sickness drugs, anti-chapped skin moisturizers, as well as standing cooling oil, mercuric chloride, thermometer, alcohol cotton, band-aid and norfloxacin. We should also prepare some vitamin drugs and take them properly to prevent vitamin deficiency. Once you catch a cold at high altitude, emphysema is easy to occur, so you should also put some cold medicine in the medicine bag. Once you have symptoms such as stuffy nose, cough and fever, you should take the medicine immediately. Choose the right equipment and bring enough cash. It should be reminded that tourists visiting Tibet should bring enough cash. Credit cards can be used in Lhasa, but not in most other counties and towns. Visitors who like to take photos and photography can bring their own cameras and binoculars, but visitors must pay attention to the warmth and moisture of these devices, otherwise they will "crash" at critical moments. When traveling in summer, in addition to the necessary daily necessities, individuals should also take rainproof, ultraviolet-proof and mosquito-proof items and prepare a thick coat. There is a big temperature difference between day and night in summer in Tibet, and the temperature is high at noon, which requires heatstroke prevention and cooling, while the temperature is low in the morning and evening, so we should pay attention to keeping warm. Generally, clothes with different thermal properties should be worn at different altitudes, and clothes and quilts should be increased or decreased in time at different temperature intervals. The basic principle is "it should be warm but not cold". Also, pay attention to environmental protection! ! ! ! Have a nice trip! ! ! ! ! ! ! ! ! ! !
