Works of three modern art pioneers, Wu Guanzhong, Zao Wou-ki and Chu Teh-chun, who went to study Western art in Paris at the beginning of the last century, will be under the hammer in April at a Hong Kong auction.

These modern masters' works to be auctioned were displayed at Beijing's Guardian Art Center on Saturday. After a traveling exhibition in Beijing, they will be sold at China Guardian Hong Kong's spring auction at the beginning of April. It's the first time for the auction house's Hong Kong auction to show their works in Beijing.
