Tan Ndjiang Nio (1825–1870), better known as Njonja Majoor Be Biauw Tjoan, was a Peranakan aristocrat of the 'Cabang Atas' elite of the Dutch East Indies (now Indonesia).
[1][2][3] A lynchpin of her class, she was the wife, daughter, granddaughter, sister, daughter-in-law and mother-in-law of Semarang's Majoors der Chinezen.
[2] The only child of her marriage to Majoor-titulair Be Biauw Tjoan, Be Tiong Khing, was married to Liem Liong Hien, who succeeded his in-laws as Majoor of Semarang from 1885 until 1904.
[3] Tan Ndjiang Nio died in 1870 at the height of her family's power, wealth and influence.
[1][2] The historian Liem Thian Joe dubbed her Kim Ki Giok Hiap, likening her to a tree with branches of gold and jade in reference to her Chinese mayoral pedigree, marriage and posterity.
