Chinese top actress Zhang Ziyi's photo of Song Jong-ki and her daughter on her social media account (Yonhap)

Chinese top actress Zhang Ziyi has spoken very highly of South Korean actor Song Joong-ki on her social media account.

"Your 'husband' is really a warm and lovely person. Xingxing, are you pretending to be cool (in Song's embrace)?" she wrote on her Weibo account, the China's equivalent of Twitter, on Saturday.

Xingxing is her daughter's nickname, and "husband" is commonly used among Chinese fans to refer to Song as many hope to marry him. She accompanied the message with a photo of Song holding her baby girl.

The post went viral, attracting more than 13,000 replies as of Sunday.

The "Descendants of the Sun" star Song signed a contract with Chinese cosmetic brand Proya in April, a company that Zhang has also endorsed. (Yonhap)
