Does the name "China" has to do something with "energy" ?

The English word "China" and prefix "Sino-" probably came from "Qin" (pronounced halfway between "Chin" and "Tsin"). Others believe that China may have been derived from the Chinese word for tea (cha) or silk (Chinese si, Latin seres). In any circumstance, the word China passed through many languages along the Silk Road before it finally reached Europe. The Western "China", transliterated to Shina (支那) has also been used by Japanese since the nineteenth century, and has since evolved into a derogatory term.

The term "China" can narrowly mean China proper, or, more usually and inclusively, China proper and Manchuria, Inner Mongolia, Tibet, and Xinjiang; the boundaries between these regions do not necessarily follow provincial boundaries. In many contexts, "China" is commonly used to refer to the People's Republic of China or mainland China, while "Taiwan" is used to refer to the Republic of China. Sometimes informally, especially in the English and Chinese business world, "the Greater China region" (大中華地區) refers to China.

Sinologists usually use "Chinese" in a more restricted sense, more akin to the classical usage of Zhongguo, or to the meaning of the "Han ethnic group", who make up the bulk of Mainland China.

Avatars refer to a concept that is not any different at all from your "real" name as also only concept. This is a spiritual question because, in fact, there is nothing such as a You that exists. The You/Me/I which folks think they are is a linguistic convention for something that exists only in a dualistic consciousness. Importantly and ultimately, there is not a You and Your Life. There is not God except as your dualistic consciousness thinks one up. Knowing this or even just acting as if this were true changes behavior in a positive way. Thinking there is a God usually (not always) results in the worst kind of behavior because of the divisive delusion and ultimate arrogance it is based on. The practice of remembering and reminding one's "self" this is usually called religion in the broadest sense. Kshetra means a field of action and a holy place - sometimes site of a war - which affects consciousness in the way that physics describes reality. The World Trade Center Site in New York is one such Kshetra.

No, no. China isn't called China in China. It's called Chungguo, or Middle (Central) Kingdom.

China is the name westerners got for the place when the Qin (pronounced chin) dynasty was in charge. Sort of like India for land of the Hindus, or Ireland for land of the Erin.

a good question... in chinese it means the "central empire "
