I have heard of this great American lady before, but not too much until I found a reportage about her at:  https://www.toutiao.com/a6633615954544689672/.  Then I also found a video about the story of her and her family in China at: https://www.youtube.com/watch?v=4-0bFzzJLzw.  I hope you would like both of them.

P.S.  I am leaving for San Francisco tonight.  I may skip my writing a couple days; see you guys later.
