(庆国庆 )
Celebration of National Day

看世界沧海桑田,
庆中华成立四九年.
中华美德源流长 国庆兼颂抗洪胜利
Great changes have taken place in the world.
Warm celebrations of the founding of PRC in 1949.
The good virtue of Chinese people is of long time.
Celebrations of National Day together with the success of resisting the flood.

华夏河山遍红旗,
All over China are red flags.
中原内外皆兄弟.
Across the country are brothers.
南辗北转实不易,
A hard time roaming north and south
念往昔,
Thinking of the old time
岁月峥嵘应有忆.
We still remember the glorious years.
洪魔肆虐似无敌,
How terrible the flood seemed!
众志成城经有计.
How courageous were the people ensured!
军民共筑卫国堤
People and army together built the dam

(英雄辈出焕荣光. )
Generations of heroes showed their glory.
