    I did hear that the nine dragons are eight peaks in present-day Kowloon, including the Lion Rock and Tate's Cairn.  The ninth dragon is the Sung empirer.  But this was probably the second last empirer who died near Tuen Mun or somewhere in the western part of Hong Kong, plunge into the sea.  The very last empirer was perhaps a brother to the second last, and died at Humen 虎門 near Guangzhou and Dongguan in Guangdong.
