从历史上看,造成华人移民的一次最大机会便是1906年发生在旧金山的那次大地震。它毁掉了这座城市的出生记录。在无证可考的情况下,大批华人可以声称自己出生在美国,因此是美国公民。事买上,他们也就是这样做的。更为重要的是,他们所有的孩子,即使有的是在中国出生的,也随之获得了美国国籍。华人的生活依旧受到很大的束缚,居住条件也十分简陋。他们住在旧金山的“飞地”(在一国境内的外国土地)上。该地区被称为“大府”——大城市。萨克拉门托是“乙府”——二等城市。单身汉10-12人住一屋,几家合用一个厨房和一个厕所。他们无法在别处找到房子,因为白人不卖也不租给 Historically, one of the biggest opportunities for Chinese immigrants was the great earthquake that took place in San Francisco in 1906. It destroyed the city’s birth record. In the absence of a valid certificate, a large number of Chinese can claim that they were born in the United States and are therefore American citizens. When things are bought, they do just that. More importantly, all their children, even those born in China, have also acquired American citizenship. Chinese life is still subject to great constraints, living conditions are also very simple. They live in San Francisco’s enclave (on foreign land within a country). The area is known as the “Grand Palace” - a big city. Sacramento is “B House” - second-tier cities. Bachelors 10-12 people live in a house, a few share a kitchen and a toilet. They can not find a house elsewhere, because whites do not sell or rent
