不敢称为学术报告,第一,我的研究比在座的许多专家浮浅得多,在座的许多都是我的师辈,比如邹衡老师给我上过一段时间的考古学课。其他许多专家对汉民族的研究也比我专深。第二,我自1999年患脑梗塞住院之后,一直不能做长时间深入思考,这次从医院出来只有十多天。原拟不来了,霍彦儒同志打电话说石兴邦、张岂之二老提名要我讲一下,老师发话了,点了名,我不敢不来。 Not daring to call academic reports. First, my research is much more superficial than many of the experts here. Many of you here are my teachers, for example, Zou Heng gave me some time in archeology. Many other experts on the Han nationality research is also deeper than me. Second, since I was hospitalized with cerebral infarction in 1999, I have not been able to think deeply for a long time. This time I came out of the hospital only for more than ten days. Originally intended to come, Comrade Huo Yanru called Shi Xingbang, Zhang Qizhi two old nomination to talk about me, the teacher pronounced, point name, I am not afraid to not come.
