In the morning, North Korean people lay flowers and pay respect to the statues or the portraits of the late North Korean leaders, Kim Il-sung and Kim Jong-Il. Pyongyang residents visit the Kumsusan Palace of the Sun where the embalmed bodies of Kim Il-sung and Kim Jong-il are enshrined, and climb up Mansu Hill to bow down to giant bronze statues of the late leaders.
