The year 2018 marks the 200th anniversary of Chinese migration to Australia. China was in the late Qing Dynasty when many were thrilled by tidings of gold mine discovery in Australia. Ballarat was called the "New Gold Mountain" and some Chinese travelled there, hoping that their lives could be changed by gold. In 2018 the number of visitors to the attraction exceeded 700,000, including more than 50,000 visitors from China. (Xinhua/Pan Xiangyue)
