Lady Sin (Jyutping: Sin2 fu1 jan4; Traditional Chinese: 冼夫人), or "Madame Sin", is a well-known historical figure among Cantonese and an important figure in Cantonese folklore. Widely hailed as "the holy mother of Lingnan", she was a skilled military leader among 6th century Baiyue peoples. She helped the Sui Empire contain the mutiny of various Baiyue tribes and start the sinicization of the region, indirectly helping Lingnan evolve into her current form. There are many temples dedicated to her in the Lingnan region, resulting in her becoming a deity-like figure.
Yun Sung-wun
Yun Sung-wun (Jyutping: Jyun4 sung4 wun6; Traditional Chinese: 袁崇煥) is another prominent Cantonese historic figure. Born in late 16th century, he was a general to the Ming Empire, known for participating in campaigns against the then invading Manchu people and several military engineering programs. He was later falsely accused of treason under the Chongzhen Emperor and executed. However, he still remained a heroic figure to many Cantonese. Nowadays, Cantonese have built many monuments for Yun across Lingnan, and his catchphrase "掉哪媽,頂硬上!" (Jyutping: Diu6 naa5 maa1 ding2 ngaang6 soeng5; literally "fuck his mom, hit it hard!"; Note: this is Cantonese profanity), which he said whenever he was facing an enemy force, is common knowledge among Cantonese people. The Chinese government's removal of this phrase from one of his monuments even sparked a massive protest by Cantonese.
