(Source: VNA) Hanoi - President Tran Dai Quang on April 10 offered incense to late President Ho Chi Minh and planted a tree at the K9-Da Chong historic relic site in Hanoi’s outlying Ba Vi district.  In 1957, President Ho Chi Minh decided to choose K9-Da Chong, about 70 km from downtown Hanoi to the west on the Ba Vi mountain range, as a secret base for the Party Central Committee to work during the resistant war against the US.  From 1960 to 1969, President Ho Chi Minh worked and received many international leaders here.  Many important decisions and instructions for the cause of national liberation and reunification were issued by President Ho Chi Minh and the Party Central Committee at the site.  After President Ho Chi Minh passed away in 1969, the place was used to preserve his body until 1975.  In order to promote the historic values of the site, the Party Central Committee’s Secretariat agreed to build a memorial house to President Ho Chi Minh, which was inaugurated in 2015. The house is expected to open its door to visitors during the Liberation Day (April 30) and May Day (May 1).  Speaking with the relic site’s officials and staff , President Quang praised their efforts in fulfilling all assigned tasks, especially protecting President Ho Chi Minh’s corpse.  He also noted that officials and staff must always improve their ideology and morality in order to make the site a place where people from all walks of life, particularly young generations, are educated on the patriotism and revolutionary tradition of the nation.-VNA
