As one of the Tibet Basics Series, Tibetan Economy includes sections such as a leisure life, a brief look on the economic life, a trade of unique features, a search for development impetus, a splendid melody of modern economic development, a symphony of regional development, a green dream, etc. Due to its high altitude, the Plateau has rather thin air, with oxygen less than nearly one third of that of the plain, which has a special influence on the economy and lifestyle of the Tibetan residents.

Only then did I know it is the environment that cultivates Tibetan grand mother the leisured way of walking and behaving.
