What it is
A work by Li Zhaoxiang describing the organisation of the great imperial shipyard at Nanjing, ship types, timbers, workshops and accounts under the Ming. The yard built the ships of Zheng He's expeditions.
Although it covers Ming warships, it gives no plans of Zheng He's 'treasure ships'; their real size remains debated.
What it led to
- a record of Ming shipbuilding with figures and trades
- a source for studying the treasure ships
- a model of state shipyard administration
