To whom it may concern:

I have a question regarding the differences between the Chinese
prostitutes in Southeast Asia and those of the North America during
the mid nineteenth century?---especially in terms of the reasons for
Chinese women to became prostitutes in Southeast Asia or in North
American counties, how these reasons are similar or different? and
what cause these similarities and differences? Also I want to know how
were the treatments that these Chinese prostitutes faced in these two
distinct environments? and how did the migration law or local policies
of Southeast Asia and North America affected the lives and incomes of
these oversea Chinese prostitutes?
