Fu Zhuan
Fu zhuan is the 'fu brick' of Hunan dark tea, famous for its deliberately cultivated golden flowers (jin hua), the beneficial fungus Eurotium cristatum that speckles the brick with tiny yellow dots. The flowering step (fa hua) is the whole point of the style and the single variable that separates a good fu zhuan from a dead one. It is a classic border tea, long drunk with milk across Xinjiang, Tibet, and Mongolia to cut a fatty, meat-heavy diet.
The defining quality signal is the golden flowers: abundant, evenly distributed, bright-yellow specks throughout the brick, never greenish, black, or fuzzy (black or green mold is a fault, not jin hua). A good fu zhuan smells of grain, dried fungus, and mild sweetness rather than damp or sour. The liquor should be clear orange to amber, smooth and rounded. Coarser leaf is normal for the style, but the fermentation should feel complete and the cup clean. Poorly stored or under-flowered bricks taste flat, dusty, or musty.
Fu zhuan today is centered on Anhua in Hunan, but the style was born in Jingyang, Shaanxi, where Hunan raw tea was shipped for centuries because local conditions favored the golden-flower fermentation. Volume production shifted to Hunan in the mid-20th century. The brick is pressed loosely enough to let air reach the interior, then held warm and humid so the Eurotium cristatum can 'flower' through the cake. It was made primarily as border tea for the northwestern frontier rather than as a sipping luxury.
Gongfu: 6-8 g per 100 ml, 95-100°C, one rinse, then 10-20 second steeps extending gradually, good for many infusions. Western: 4-5 g per 250 ml, 95-100°C, 3-4 minutes. Break the brick along its layers. It also takes well to boiling or simmering and to a splash of milk in the border-tea style.
€5-25 (about $5-27) per 100 g, with everyday commodity bricks cheap and well-flowered or aged examples at the upper end.

Shaanxi Fu Cha (Jing Wei)
Shaanxi fu cha (Jingyang) is the same golden-flower brick made at its historical birthplace; the Hunan and Shaanxi versions are siblings, not different teas.
Hei Zhuan (Black Brick)
Hei zhuan is the un-flowered black brick from the same Anhua family, with no jin hua, coarser and woodier.
Hua Zhuan (Flower Brick)
Hua zhuan is the decorated 'flower brick' whose name refers to its stamped border, not to golden flowers, which it does not carry.
Liu Bao
Liu Bao is the basket-aged Guangxi dark tea; it ferments and ages without the cultivated golden-flower step that defines fu zhuan.
The golden flowers are not mold in the spoilage sense but a cultivated fungus, Eurotium cristatum, that producers encourage on purpose; a denser, more even bloom of the yellow specks is read as a mark of a well-made fu brick.
