Abstract: Cultures can be advanced or backward，and advanced culture is a timeless conception.Only persisting in learning advanced culture and conducting cultural exchange with the attitude of cultural bequest can people preserve their own national traditional culture and keep cultural diversified.This is not only a starting point for cultural communication，but also a standpoint for sinological education and communication.The cultural dimension which contains multiple meanings is essential to sinological education and communication.Firstly，during the process of educating and communicating，it is necessary to persevere in autonomy and subjective consciousness to one's own national culture.Secondly，the meaning of the cultural dimension also includes the target or orientation of the sinological education and communication，that is，we should aim at cultivating and improving juveniles'cultural quality and enhancing national cultural deposits in their mental structure.Thirdly，the way of educating and communicating is supposed to be detailed and life-oriented.Only if the sinological education and communication is integrated into the daily life of common people and become the basic elements of their way of life，it can play its due role.If not，it will be dead knowledge in books or Confucian masters'teaching materials forever，and have no concern with inheriting and developing the excellent national cultural tradition.
