The relationship between temperature changes of China and the whole world is revealed by using the temperature data on the global grids and over Chinese 160 stations from 1951 to 1989. After combining the data on the global grids with that over China, the EOF is applied to this united data set. It's found that North China where the annual temperature warming trend is clear, if looked from the global background, is a part of the warming region centered over center north Eurasia, whereas the decreasing trend of temperature in south-west China is a local phenomenon. The space-time structure of annual temperature variation is mostly due to winter temperature anomalies. The warming trend of winter over most part of China is accompanied with the warming(cooling) trend over Eurasia and North America(North Pacific and North Atlantic), which is attributed to the strengthening of zonal(meridional) circulation over Eurasia (North America).The trend of summer temperature over the Changjiang River Basin is opposite to that over South Asia: the summer temperature is decreasing over the Changjiang River Basin and increasing over South Asia.
