Finally, I will remember 14-year-old Li Tangmo and his 7-year-old sister Qingyi, whose parents were killed in the earthquake. I met them at a shelter in a small stadium. They were being looked after by an uncle and were waiting to find out whether he and his wife would take them in for good.
Li Tangmo told us bravely that he and his sister would go somewhere else if their uncle and aunt didn't want to care for them. He sobbed as he spoke to us. Of all the stories I've covered in my time in China, theirs was the one which affected me the most. A year later, I don't know what's happened to the brother and sister - but I think of them often.
