Heihe–Tengchong Line

The Heihe - Tengchong line (Chinese黑河-腾冲 线/黑河-腾冲 线, Pinyin Heihe - Tengchong Xian), also called Aihui - Tengchong line is an imaginary line that divides China's space into two approximately equal parts.

It is diagonal drawn across China from the place Heihe (Chinese黑河, Pinyin Heihe ) ( Heilongjiang Province ) to Tengchong (Chinese腾冲, Pinyin Tengchong ) ( Yunnan Province ) and was already in 1935 by the Chinese population geographers Hu Huanyong as "geo - demographic demarcation line" (geo -demographic demarcation line ) respectively.

This imaginary line divides the territory of China as follows:

• West of the line: 57 % of the area, but only 4 % of the population (1935 );
• East of the line: 43 % of the area, but 96 % of the population (1935 ).

Although already more than 70 years have passed since then, the basic results remain - certainly weakens over time - Valid: The 1990 census gave a ratio of 5.7 % of the population west to 94.3 % of the population east of the line. In the census in 2000 the ratio was 9.2 % to 90.8 %. Thus east sank the population from 1990 to 2000 from 1,182 to 1,151 million, while they rose from 65 in the western part to 116 million, and thus held the overall increase of the Chinese population only in the western part.
