 ''' Samjeondobi Monument , Seoul ''' 
 This monument was erected at the request of Qing China in 1639 , shortly after the Manchu invasion of 1637 . 
 On January 3 , 1637 , the Qing troops crossed the Amnokgang River . Six days later , King Injo ( r . 1623 - 1649 ) and his ministers took refuge in Namhansanseong Fortress to defend themselves against the invaders . After withstanding 47 days of siege , King Injo went to surrender at the ferry dock of Samjeondo , where the Qing troops were staying , and was forced to accept vassal status to Qing . Later , the Qing Emperor Hong Taiji ordered a monument to be erected at Samjeondo , praising his excellent virtues .
