Hung Lau is a house built between 1905 and 1910 on former farmland in Pak Kok, Tuen Mun, Hong Kong. It was used by the Revive China Society () as a base for revolutionary activities against the Qing dynasty. Nature and locale It is a Grade I historic building since 2009, a classification which does not mandate preservation. It is named for its red-pigmented external surface rendering. The two-storey house is a mix of Chinese and Western influences. It is near the Tuen Mun Public Riding School, Butterfly Estate and Castle Peak. History Hong Kong merchant and financier of the original China Daily Li Ki-tong, who met Dr. Sun Yat-sen in 1895 and joined the Revive China Society in 1900, provided his farm to the Society as its secret base in 1901. The farm provided cover and sustenance to the group for the planning of its coup attempts in Guangzhou and Wuhan. In 1968, a proposal was made by lawmaker Ellen Li, specifying that a memorial garden and museum be set up in the area. The proposal was declined because British colonial officials did not want to collaborate with the pro-Taiwan Sun Yat-sen Memorial Association of Hong Kong, a group which made repeated requests for the conservation of the site. In the 1990s and early 2000s, the District Council of Tuen Mun proposed spending HKD $86M to restore the area, but it did not move forward. The house and garden remained in the Li family as of 2011 but was subject of a controversial sale to a mainlander in November 2016 for HKD $5M. In February 2017, 300 people protested the demolition of a wall by the new owner. It was declared a proposed monument by the Antiquities Advisory Board on 9 March 2017 to protect the building from further modifications and damages, for a period of one full year. In October 2017, the owner applied for a subsidy from the government, which mandated that the building should not be demolished or sold 10 years after restoration. In December 2017, the government decided to not promote the building as a declared monument, due to lack of concrete evidence linking the building to the 1911 revolution. Since the Double Tenth Festival in 2018, celebrations of the Republic of China National Day and Establishment Day have been blocked by the owner, saying participants are not allowed to enter the grounds on those
