and thirty years out, from the war,

战争过后30年
with the transmission--

[人们的想法]发生了转变
and we know this about so many events

也发生了许多事
and the way generations learned from one another

几代人相互学习
and the way memory gets passed on--

内战的记忆也得到了传承
as soon as there is truly a generational transition,

这代老兵的想法也发生了转变
the old veterans, as they get older, are willing to come.

年事已高的老兵愿意来重聚
The 1900 Blue-Grey Reunion was held in Atlanta.

1900年在亚特兰大举行了蓝灰重聚
And by the way,

以此为契机
Southern cities started to compete for these things just like Northern cites,

南方的城市也开始像北方的那样相互竞争
because they were huge moneymakers.

因为重聚能带来客观的利润
Thousands and thousands of veterans would come with their families

成千上万个老兵会带着他们的家人
