"A man who does not plan along ahead will find trouble at his door"--Confucius

Due to the special geographical location of Tibet, high altitude and complex and diverse natural climate, it is essential to make adequate preparations before the dream vacation. on the other hand, Tibet is a completely unfamiliar destination for me, so comprehensive plan will make us enjoy more scenery more comfortable and save more time. 

Top 8 things should be considered before go to the Tibet. 

• A good mental preparation : a good psychological quality is the best way to overcome altitude sickness. Large number of examples proved that keeping open-minded optimism could weaken the physical discomfort caused by altitude sickness. 
• A good body requirements : Before go to Tibet people should exercise regularly and maintain a good physical condition. 
• Some medicine : some conventional cold medicines, gastrointestinal drugs and some medicines anti-altitude sickness, etc. 
• Different clothes : Because of the large temperature difference in Tibet, people should bring pieces of clothing. In the morning and evening it will be extreme cold, people should wear as much as possible. However, in the noon it will becomes hot, people could appropriate takes off some. 
• Both sunlight and ultraviolet radiation in Tibet are very strong, so people should be sure to bring sunscreen, hat and sunglasses.

• SLR Cameras : Tibet beauty numerous, SLR cameras could maximize record the views meticulously. 
• Useful Tibetan greetings : Tibetans are very honest and hospitable, helpful Tibetan greetings are essential. ;)
