XI'AN, July 25 (Xinhua) -- Over 100 teachers from the special administrative regions of Hong Kong and Macao participated in a Mandarin training course in northwest China's Shaanxi Province.

The 10-day training course, beginning on Tuesday, included Mandarin learning and tests, and academic lectures.

Besides language study, the teachers will visit several historic places of interests in Xi'an, capital of Shaanxi, such as the famous Terracotta Warriors.

"The course gave us an opportunity to improve our Mandarin and deepen understanding of our culture," said Tse Lai-Wah, a primary school teacher from Hong Kong.

The first course was held in 2016 and more than 300 teachers have been trained since then.
