Chinese navigation day
On 11 july, the 20th chinese day of navigation, the theme of which was “wise to sail the future”. Let's sail together, take a little boat with a pocket dictionary, swim the wonderful sea world and explore the treasure of the ocean
This pocket dictionary will focus on marine knowledge and lead you to the scientific terms that are relevant to navigation。
Let's learn, grow together, become explorers of knowledge of the oceans
Zheng and xiyang
Zheng he xi yang
Explanatory note: since myung-zu, eunuch zheng and her fleet have conducted seven long voyages to the countries bordering the south sea and the indian ocean. Launched in 1405 a. D., until 1433, when zheng and the sick were on their seventh voyage home. More than 30 countries and territories across asia and africa have significantly expanded ming dynasty's external relations and influence and represent the highest level of navigation technology at that time。
