青山灣
In the present day, "Tunmen" refers to Tuen Mun, the Cantonese reading of the same Chinese characters. This leads some researchers to link the Tunmen of Ming times to Tuen Mun in the New Territories of Hong Kong. "Tunmen Inlet" would then refer to one of two bays around Tuen Mun: Castle Peak Bay, next to the current Tuen Mun New Town; or Deep Bay between the New Territories and Nantou in present-day Shenzhen, where a Ming coastal defense force was stationed.
