学海无涯,并无完人。即使在权威学者的著作中也难免偶尔出现一点小的纰漏,这有多种原因。有的因为当时条件所限,无法得见有关的重要资料;有的由于时日仓促,未暇全读相关书籍;也有的出于记忆有误,未经考证这些情况的产生,都并非学者本身的根本问题,只不过稍有不足之处而已。 There is no perfect sea to learn. There are many reasons why it is inevitable that there may be occasional minor flaws in the writings of authoritative scholars. Some of them were unable to obtain the relevant important materials because of the limited conditions at that time. Some did not have enough time to read the relevant books because of the rush of time. Others did not study the books without reading due to their mistakes. The fundamental problem, but only a slight deficiencies only.
