Rear Admiral Zheng Ming(Retired) Summary and Foreword]This paper cited plenty of treatises and information of scholars of our time，and the author only contributed to some colligations and integrations．Some viewpoints are elicited mostly via the individual thinking and analysis based upon many scholars’opinions，SO the author takes sole responsibility for his views．Hopefully it can touch off discussions，promote studies，seek common views on the orginal historical features of Zheng He’s ancient ship and science，get to timely guidance on and implementation of Zheng He’s treasure ship restoration project．
