According to Korean legend, the princess of Ayodhya went to Korea in 48 AD and married king Kim-Suro.A large number of Koreans trace their ancestry to this legendary princess, who is known as queen Heo Hwang-ok. "The legend of queen Heo Hwang-ok binds the two countries together culturally and her (Kim's) visit will further promote our people-to-people ties," a senior official at the cultural wing of the South Korean Embassy in India told PTI.An agreement regarding the Queen Suriratna Memorial Project was signed to facilitate the upgrade and expansion of the existing monument, commemorating princess Suriratna (queen Heo Hwang-ok).In July, the two countries had signed the agreement for the expansion of the Suriratna memorial project.Uttam Das, a seer from Ayodhya, told PTI, "It was a matter of honour for Ayodhya that she (Kim) visited the place." "A princess of Ayodhya had gone to Korea around 2,000 years ago and now, the first lady is visiting Ayodhya. Life has come full circle," he said.As part of the Deepotsav festivities, a Ramlila was performed by artistes from Russia, Laos, Cambodia, Indonesia and Trinidad and Tobago.On Wednesday, Kim is scheduled to go to Agra to visit the Taj Mahal.
