From the videos I watched on YouTube. Abby was a well known socialite in Hong Kong. She was born into a wealthy family with businesses in mainland China. Her mom is also a popular influencer in China, her name is 五姐.

She met her ex-husband Alex when she was 15 and married him at the the age of 18 and had two kids with him. Due to personality differences, they divorced and she later married (marriage was not registered) famous restaurant chain Tam Jai Rice Noodle founder’s son Chris and had two kids with him. They probably agreed to not register their marriage as they are both wealthy and want to have their finances seperate (just my assumption).
