Biography

Kei earned her bachelor's degree in economics from the London School of Economics.

Through a family trust and several corporate entities, she controls 85% ownership of Logan Property Holdings (), where she serves as a non-executive director. Logan is a prominent real estate development company operating primarily within China, led by her father, Ji Haipeng, who holds the positions of chairman and CEO. The company is based in Shenzhen, near Hong Kong, generated US$1 billion in revenue in 2012, and completed its initial public offering in December 2013.

In 2010, Kei became a non-executive board member of Logan. That same year, Logan Property was established in the Cayman Islands with Kei listed as the sole shareholder. Gradually, she acquired majority ownership via multiple holding companies registered in the British Virgin Islands and a family trust located in Guernsey. As a Chinese national, offshore assets typically require declaration and taxation within China; however, after obtaining residency in Hong Kong in 2012, Kei's offshore shareholdings and dividend income are exempt from Chinese tax disclosure obligations. Additionally, she holds citizenship from Saint Kitts and Nevis.

When her father transferred control of their business interests to the Cayman Islands under her name, he subsequently regained ownership, which resulted in a substantial reduction of her estimated personal wealth.
