I want to introduct something about Handcraft Comb.
Specifications:Changzhou wooden & bamboo combs have a history of 1500 yaers.They are China’s traditional handicraft articales,known as “Palae Combs” and were one of the eight famous hair decorations in the ancient time in our country. Changzhou wooden & bamboo combs have been awarded medals for eleven times at various exhibitions both at home and aboard in nearly one handred of years. E.g. a silver medals at Panama International Peace Exhibition in 1915, a golden medal at the U.S. Philadelphia Fair in 1926. Made of choice material,the combs under go carving,cutting,painting and scorching which make them singularly beautiful and uniqui in style. These combs are beautifully shaped with more than 700 patterns,among them there are historial people,birds,and beasts,flowers and fishes,landscapes.It is not only a necessity of daily life,but also a mice gift for friends.

Papyrus plant (Cyperus papyrus) at Kew Gardens, London
Cyperus papyrus (papyrus sedge or paper reed) is a monocot belonging to the sedge family Cyperaceae. It is a herbaceous perennial native to Africa, and forms tall stands of reed-like swamp vegetation in shallow water.
Papyrus sedge (and its close relatives) has a very long history of use by humans, notably by the Ancient Egyptians it is the source of papyrus paper, parts of it can be eaten, and the highly buoyant stems can be made into boats. It is now often cultivated as an ornamental plant.

Description
This tall, robust, leafless aquatic plant can grow 4 to 5m (13 to 16ft) high. It forms a grass-like clump of triangular green stems that rise up from thick, woody rhizomes. Each stem is topped by a dense cluster of thin, bright green, thread-like stems around 10 to 30cm (4 to 10in) in length, resembling a feather duster when the plant is young. Greenish-brown flower clusters eventually appear at the ends of the rays, giving way to brown, nut-like fruits.
The younger parts of the rhizome are covered by red-brown, papery, triangular scales, which also cover the base of the culms. Botanically these represent reduced leaves, so strictly it is not quite correct to call this plant fully “leafless”.
Papyrus in history
Main article: Papyrus
Papyrus paper
Egyptians used the plant for many purposes, most famously for making papyrus paper. Its name in Greek and in English is widely believed to have come from Egyptian, but this is probably a folk etymology. Cyperus papyrus is now used mainly for decoration, as it is nearly extinct in its native habitat in the Nile Delta, where in ancient times it was widely cultivated. Theophrastus’ “History of Plants” (Book iv. 10) states that it grew in Syria; and, according to Pliny’s Natural History, it was also a native plant of the Niger River and the Euphrates.
Aside from papyrus, several other members of the genus Cyperus may actually have been involved in the multiple uses Egyptians found for the plant. Its flowering heads were linked to make garlands for the gods in gratitude. The pith of young shoots was eaten both cooked and raw. Its woody root made bowls and other utensils and was burned for fuel. From the stems were made reed boats (seen in bas-reliefs of the Fourth Dynasty showing men cutting papyrus to build a boat; similar boats are still made in the southern Sudan), sails, mats, cloth, cordage, and sandals. Theophrastus states that King Antigonus made the rigging of his fleet of papyrus, an old practice illustrated by the ship’s cable, wherewith the doors were fastened when Odysseus slew the suitors in his hall (Odyssey xxi. 390).
The “rush” or “reed” basket in which the Biblical figure Moses was abandoned may have been made from papyrus.
The adventurer Thor Heyerdahl built two boats from papyrus, Ra and Ra II, in an attempt to demonstrate that ancient African or Mediterranean people could have reached America. He succeeded in sailing Ra II from Morocco to Barbados.
Ecology
Papyrus ranges from subtropical to tropical desert to wet forests, tolerating annual temperatures of 20 (68) to 30 (86) and a pH of 6.0 to 8.5. Papyrus flowers in late summer, and prefers full sun to partly-shady conditions. Like most tropical plants, it is sensitive to frost. In the United States it has become invasive in Florida and has escaped from cultivation in Louisiana, California and Hawaii.
Papyrus sedge forms vast stands in swamps, shallow lakes, and along stream banks throughout the wetter parts of Africa, but it has become rare in the Nile Delta. In deeper waters it is the chief constituent of the floating, tangled masses of vegetation known as sudd. It also occurs in Madagascar, and some Mediterranean regions such as Sicily and the Levant.
The “feather-duster” flowering heads make ideal nesting sites for many social species of birds. As in most sedges, pollination is effected by wind, not insects, and the mature fruits after release are distributed by water.
In recent years papyrus has been the subject of intense ecological studies centered around its prodigious growth rate and ability to recycle nutrients. Much of this research was begun at Makerere University in Uganda in the early 70 in the swamps on the edge of Lake Victoria and continued in Kenya (University of Nairobi) on Lake…(and so on)
