Angela Leong On-kei, the "fourth wife" of Macao's casino magnate Stanley Ho Hung-sun, led some 100 staff members from her company to visit Jinggang Mountain in Jiangxi Province, which is dubbed the "cradle of the Chinese revolution," to receive a three-day patriotic education course, news portal chinanews.com reported on Friday.

The staff members of casino operator SJM Holdings, in which Leong is the managing director, will receive course including placing wreaths at the cemetery of revolutionary martyrs and communicating with descendants of Red Army veterans, the report said.

"Helping staff increase their understanding of the country and raising their spirit to 'love the country, love Macao' is one of my responsibilities," said Leong, who is also a member of the Jiangxi provincial committee of the Chinese People's Political Consultative Conference.

She also donated 300,000 yuan ($48,450) to three local farms, the report said.
