1998年6月的一天,我在德钦县的荣中村调查,快到做中午饭的时间,便去买豆腐。做豆腐的人是村小学的退休教师李鸿基。他一头白发,风度儒雅。他说自己本来退休后可以不干活,但整天看书太累,身体也不太好,要活动活动,于是操起以前的手艺做豆腐。李老师不忙着拿豆腐,却请我们到二楼的书房坐坐。当地的藏族人家,有佛堂但无书房,惟独李老师家例外。一张桌子,一些散堆着的书籍,一把圈椅。坐下,李老师就聊起家常。他说他的祖辈人来自大理鹤庆,是白族,这让我十分好奇。他怎么来到藏族 One day in June 1998, I surveyed Rongzhong Village in Deqin County. It was almost time for lunch to buy tofu. People who make tofu are Li Hongji, a retired teacher from a village elementary school. He has a white hair, graceful. He said he could have quit working after retirement, but reading books too tired all day, the body is not very good, to activities, so start with the previous craft tofu. Mr. Lee is not busy with tofu, but we asked to sit on the second floor of the study. Local Tibetan people, there is a Buddhist temple without a study, except for the exception of Teacher Li. A table, some scattered books, a circle chair. Sit down, Teacher Li chatted on homemade. He said that his grandparents came from Dali Heqing, a white clan, which made me very curious. How did he come to Tibet?
