The New Territories is one of the three major geographical districts of Hong Kong, China (the other is Hong Kong Island and Kowloon). The largest part of the Hong Kong Special Administrative Region, the New Zealand hills and undulating, is the highest place in the region. The 957-meter-high Mount Taishan is the highest peak. According to the 2001 Hong Kong Census, the total population of the New Territories is 3,343,046, accounting for 49.8% of the population of Hong Kong. Geographically, the New Territories can be counted as an island and does not border China. The reason is that the source of the Shenzhen River is almost the same, and the Shenzhen River even penetrates the entire Hong Kong-Shenzhen border. The name of the New Territories was on June 9, 1898, when the British Government and the Qing government signed the "Exhibition of Hong Kong's Borders" in Beijing. Since the newly leased land does not have a unified name, it can be referred to as the "new concession".
