Kim Liên commune holds two sites, and telling them apart matters. Hoàng Trù was his mother's family village, and it is where he was actually born; its temple stands about two kilometres from the museum. Làng Sen was his father's village, and that is where the boy lived until 1895, when his father sent him south to Huế to study. His mother, Hoàng Thị Loan, was the daughter of the scholar who had adopted and taught her husband — the marriage was made inside a household rather than between strangers, which is how two neighbouring villages ended up carrying the same family's story between them. Guides tend to run the sites in order: born at Hoàng Trù, raised at Làng Sen, gone by the age of five.

The site is often described as the family's home during Nguyễn Sinh Sắc's service as a vice-magistrate. That is not what he was doing here. Born in 1862, Sắc was in these years a Confucian scholar and village teacher, working toward the imperial examinations rather than holding office under them. He passed the cử nhân degree in 1894 and took the higher phó bảng rank in 1901, and it was only in 1909 that he was appointed a magistrate — in Bình Khê, in Bình Định province, several hundred kilometres down the coast. That appointment ended badly. A landlord he had ordered caned died shortly afterwards, and Sắc was demoted for abuse of power. He died in 1929, thirty-four years after his son left this village, and long before the name Hồ Chí Minh meant anything to anyone.

Cung learned to read from his father before being handed to a local scholar, Vương Thúc Quý, and he took quickly to chữ Hán, the classical script that any serious study of Confucianism demanded. He also flew kites and went fishing — the sort of detail that only survives in a biography because of what the child later became. He had a sister, Nguyễn Thị Thanh, who worked as a clerk in the French army, and a brother, Nguyễn Sinh Khiêm, who grew up to be a geomancer and herbalist. Another brother, Nguyễn Sinh Nhuận, died in infancy. Following Confucian custom, his father gave him a new name when he turned ten: Nguyễn Tất Thành. There would be dozens more before the last one stuck. He also gave four different birth years at various points in his life, so even the 1890 on the placard is the accepted answer rather than a settled one.

The 1959 rebuild is the honest part of the site. Thatch and wattle do not survive long in this climate, and reconstruction was the only way to show visitors anything at all; what went up reproduces a modest scholar's cottage rather than improving on it. The buildings that grew around it are a different matter. Much of the surrounding complex is raised in Vietnamese temple architecture — the vocabulary of shrines and ancestral halls — and none of it existed when the family lived here. A boyhood home has been given the grammar of a place of worship, and the visitor is left to work out where the house ends and the monument begins. There is a gift shop. Admission is still free.
