A group of Rotorua principals travelled to China for two weeks last month to learn more about the culture, teaching and language.
Kaitao Middle School principal Rory O'Rourke said they were invited, with other principals from around the country, by Confucius Institute, which paid for the trip.
The trip was for schools that taught the language or were thinking of doing so, he said.
It started in Beijing where they went to the Great Wall, Forbidden City and Tiananmen Square.
Mr O'Rourke said the group also visited John McKinnon, the New Zealand ambassador to China, and a number of primary and intermediate/middle schools.
