I, as an educator, have been devoting myself to the great career of becoming an excellent communicator of scientific knowledge, a guider of exploring the unknown and a shaper of descendants' soul. Striving for gathering water from oceanic knowledge to nourish saplings; inheriting the sunlight of truth to enlighten blooms is the everlasting aspiration of mine. To this end, I read - teach - write - book, ... Stars wheeled overhead, in the meantime,  Holding a heart to come, not to carry off half grass to go , only in order to fulfill the duty and mission.              ——Guangqiang Wu
