Zu Chongzhi was born during the Northern and Southern Dynasties. Little Zu was interested in many subjects, especially(尤其) maths.
Zu was best - known for his calculation(计算) of pi(π). According to records, he did all the work using wooden sticks. It took him lots of time to work out the value(值) − between 3.1415926 and 3.1415927. In order to remember Zu, some people call pi “Zu's ratio(祖率)”
Zu was successful not only in maths. He also thought that a year should be 365.24281481 days long and created the Daming Calendar. But officials (官员) at that time did not agree with Zu.

Zu was also an inventor. He once made a vehicle(交通工具) that carried a pointer(指针). No matter how the vehicle turned, the pointer always pointed to the south. Zu also invented the 1,000 - li Boat. The boat could travel about 50 kilometres in a day.
