The heart of the present-day Mong Kok is along Argyle Street near Sai Yeung Choi Street whilst the proper Mong Kok used to be to the north, near the present-day Mong Kok East station. Mong Kok was an area of cultivated lands, bounded to the south by Argyle Street, to the west by Coronation Road (a section of present-day Nathan Road), and to the east by hills. To the southeast of Mong Kok is Ho Man Tin and to the west Tai Kok Tsui.
