Politburo member To Huy Rua visited Thuan Thanh convalescent home for war invalids in Bac Ninh Province outside Hanoi and praised the efforts of the soldiers.
He said they had made remarkable contributions to the war for national salvation. 'You are down but not out', Rua said.
On behalf of the Party and State, he presented gifts to 97 residents living in the centre, 90 of whom were in wheel chairs.
Meanwhile, Truong Thi Mai, director of the National Assembly Committee for Social Affairs, paid a visit to Convalescent Home No 2, in Vien An, Ung Hoa District, Ha Noi.
This is where many people who also rendered service to national salvation are being looked after.
And the Vietnamese Youth Union organised many activities nationwide to show deep gratitude to combatants. They reflected that those who drank the water should remember the source.
Thousands of 'gratitude houses' have been built for hero mothers, war martyrs' families and wounded soldiers.
