Editing Tuen Mun District (section)

===Before the establishment of the district===
According to the ''Old History Book of Tang Dynasty'' ({{zh|t=舊唐書}}),{{page needed|date=December 2019}} and the ''New History Book of Tang Dynasty'' ({{zh|t=新唐書}})<ref name="book3" />{{rp|13, 16}} Tuen Mun was a major trading port, and there were garrison stationed there as early as the [[Tang dynasty]] (A.D. 618–907).<ref name="book3">{{cite book|url=https://books.google.com/books?id=_itrBgAAQBAJ|script-title=zh:屯門|series=香港地區史研究|author=劉蜀永 [Liu Shuyong]|editor1=劉智鵬 [Lau Chi-pang]|editor2=Liu Shuyong|language=zh-hk|publisher=Joint Publishing ([[Sino United Publishing]])|isbn=978-962-04-3147-0|date=July 2012|location=Hong Kong|script-chapter=zh:歷史沿革}}</ref>{{rp|16}} The geological features described by historical literature match that of modern day Tuen Mun.<ref name="book3" />{{rp|13}} However, the interpretation of the location of Tuen Mun is widely disputed, and it is suggested the historic Tuen Mun may refer to [[Nantou (historic town)|Nantou]] in the modern day [[Shenzhen]] (historically the residual part of the Xin'an County) instead. One scholar, [[Lau Chi-pang]], rebutted this interpretation in an article he wrote.<ref name="book4">{{cite book|url=https://books.google.com/books?id=_itrBgAAQBAJ|script-title=zh:屯門|series=香港地區史研究|author=劉智鵬 [Lau Chi-pang]|editor1=Lau Chi-pang|editor2=劉蜀永 [Liu Shuyong]|language=zh-hk|publisher=Joint Publishing (Sino United Publishing)|isbn=978-962-04-3147-0|date=July 2012|location=Hong Kong|script-chapter=zh:屯門與青山}}</ref>{{rp|28}}

The area around Tuen Mun, excluding [[Tai Lam]] and [[Lung Kwu Tan]], was placed under the Yuen Long ''yeuk'' ({{zh|t=約|j= joek3 |cy=yeuk }}) soon after the signing of the [[Convention for the Extension of Hong Kong Territory]] in 1898.<ref name="book2">{{cite book|url=https://books.google.com/books?id=i-ynDgAAQBAJ|script-title=zh:本土論俗──新界華人傳統風俗|author=施志明|pages=3–4|publisher=Chung Hwa Book Company (Sino United Publishing)|location=Hong Kong|language=zh-hk|script-chapter=zh:緒論|isbn=9789888420186|date=November 2016|series=香港史學會叢書}}</ref><ref>{{cite web|url=http://www.amo.gov.hk/form/chik_kwai.pdf|title=Consultancy for Conservation Study of Chik Kwai Study Hall at Pat Heung|date=January 2008 |author1=Ho Puay-peng |first2=Henry Ka-yu|last2=Lo|first3=Heidi Sze-man|last3=Lam|first4=Robin S.|last4=Howes|first5=Sophia|last5=Mak |via=Antiquities and Monuments Office|access-date=1 December 2019}}</ref> The convention leased the New Territories and New Kowloon to the British Empire as an extension of the [[Colony of Hong Kong]]. Before the lease, Tuen Mun was part of the [[Bao'an County|Xin'an County]]. In the ''[[Xin'an Xianzhi]]'' (literally ''Gazetteer of the Xin'an County'') [[Kangxi]] edition, Tuen Mun village was under the administration of ''Wu-dou'' ({{zh|t=五都}}).<ref name="Xianzhi">{{cite book|script-title=zh:新安縣志|script-chapter=zh:地理志|edition=Kangxi Years|date=1688|language=lzh}}</ref> Also under ''Wu-dou'' were [[Kam Tin]], [[Ping Shan]], [[Yuen Long]] and [[Shek Kong]].<ref name="Xianzhi" /> They are areas of the modern day [[Yuen Long District]].<ref>{{cite book|script-title=zh:康熙新安县志校注|script-chapter=zh:地理志|title=Kāngxī xīn'ān xiànzhì jiàozhù|trans-title=Kangxi's Gazetteer of the Xin'an County, with footnotes|date=June 2006|publisher=Encyclopedia of China Publishing House|orig-year=Based on 1688 edition|author=张一兵|isbn=7-5000-7512-X|language=zh-cn}}</ref>

Soon after, the [[Old District Office North|District Office North]] (Northern District, not to be confused with the modern-day [[North District, Hong Kong|Northern District]]) was established to administer the New Territories including Tuen Mun. After [[World War II]], the Yuen Long District Office was spun off from the District Office North.

Tuen Mun and its surrounding area were administratively part of Yuen Long [[District officer|District Office]] until 1974.<ref name="book" />{{rp|154}} (an author stated Tuen Mun (branch-) office was "established after 1969"<ref name="book2" />{{rp|4}}).

While originally named Castle Peak New Town during its planning, the new town of the area was finally named [[Tuen Mun New Town]], adopting the historic name of the region in 1972.<ref name="book">{{cite book|url=https://books.google.com/books?id=_itrBgAAQBAJ|script-title=zh:屯門|series=香港地區史研究|editor1=劉智鵬 [Lau Chi-pang]|editor2=劉蜀永 [Liu Shuyong]|script-chapter=zh:屯門新市鎮的發展|language=zh-hk|publisher=Joint Publishing (Sino United Publishing)|isbn=978-962-04-3147-0|date=July 2012|location=Hong Kong|last=黃 [Wong]|first=君健 [Kwan-kin (Kenneth)]}}</ref>{{rp|151}} The new town was built on [[land reclamation|reclaimed land]] from the [[Castle Peak Bay]], as well as levelled hillside areas starting from the 1960s.

The New Town also incorporated [[Tuen Mun San Hui]], a rural market township, as part of the New Town's town centre.
