In 1802, a civil service mandarin named Tran Tu Nhuc built a family home and chapel to worship his ancestors. A favorite of Viet Emperor Gia Long, he was sent to China as an ambassador, and his home reflects his high status. Elegantly designed with original Chinese antiques and royal gifts such as swords, two parts of the home are open to the public: a drawing room and an ancestral chapel. One roof tile has been replaced with transparent glass, allowing a single shaft of light to slice through the chapel and onto the altar in the morning. The house does a splendid job of conveying all that is exotic and interesting about these people and their period. The drawing room has three sections of sliding doors: the left for men, the right for women, and the center, open only at Tet and other festivals, for dead ancestors to return home. The ancestral altar in the inner room has small boxes behind it containing relics and a biography of the deceased; their pictures hang, a little spookily, to the right of the altar. A 250-year-old book with the family history resides on a table to the right of the altar. Beside it is a small bowl, containing yin and yang coins, meant to bring good luck. Give them a toss, and if they land one yin and one yang side up, you are on your way to prosperity. I got it on my first try, but the guide will give you three chances. In back of the house are a row of plants, each buried with the placenta and umbilical cord of a family child, so that the child will never forget its home. As if it could.
