The new annals of Tang (新唐书) recorded that "Tibetans usually wear in brown and have sunglow hat on their heads,men or women all wear their hair pigtails." Collected works of Dunhuang Grottoes mentioned that Tsenpo wears a Sunglow hat and red head bands. We can also find some red top hats in NO. 159 grotto in Mo Gao which is considered to be one typical kind of Sunglow hat. The word "sunglow" ,whose Chinese pronunciation is "Zhao Xia", actually means the red tussah silk imported from Korea. Records of Tang(唐会要) recorded that Tibet, where is considered not suitable for cotton cultivation, also pays Sunglow silk as tribute to Tang.The new annals of Tang also recorded this kind of silk was imported through Protectorate of the Western Regions(安西都护府,An Xi Protectorate).Sunglow hat is usually as red as morning glow, it's a straight hat that twine the wearer's head. We can see from top of the hat that the fabric texture of it is quite thick, both red and white top sunglow hat have been funded and the hat usually reveal a white edge on the bottom. I guess that Tibetan sunglow hat should be made of fur or linen stripes as Tibet is not suitable for cotton cultivation. Those fur or linen stripes usually have one or two 15cm-wide-white hemmings to form a white top and bottom hat.
Sunglow hats and red head bands can be worn together. Tibetan noble men usually wear Sunglow hats first and then use red head bands to fasten the hat, the portrait of Tsenpo in NO. 158 and 159 grotto shows this, the Tsenpo wears a red silk fabric,which is considered to be part of red head band.
2. Red head band
Red head band can be used alone or together with Sunglow hat. Low ranking retinues and common usually use the red head band exclusively. An example is picture in NO. 231,a retinue standing in front of Tsenpo wears a red head band. Red head band is shorter and narrower than Sunglow hat, but its softer. Red head band is not always red, for example, the retinue in the picture of NO. 231 grotto wears a dark red head band with bluish green figures on it.
3. Bight caps.
Pro. Xie Jing 's view is that the kerchiefs appeared in NO. 225 and NO. 220 grotto are bight caps, more over, she also considers the hat appears on wooden coffins unearthed in Qinghai to be bight caps. But according to my study, they are actually different. Obviously we can see the retinue in the picture of Dunhuang wears a red head band, which twines his neck and leave his hair exposed on the top. While the man on wooden coffins of Qinghai wears a bight cap, which is thicker and wraps the whole head, sagged to his waist. Bight cap has many color types, its much longer than the red head band and softer than Sunglow hat. Bight cap is considered to be one kind of early Tibetan clothes, while the period of Red head band is after 780 ad, when Tibet's occupation of Dunhuang.
4.Towering kerchief
Pro.Xu Xinguo believes that the Tsenpo hunkers tent and the noble men who pull their bow in pictures on wooden coffins of Qinghai wear towering kerchiefs.The picture of Illustration of Raudraksa also depict a man wearing towering kerchief. Towering kerchief is similar to Sunglow hat but its longer and has a sharp, forerake top. Towering kerchiefs are usually red, but there are some other colors like white and brown. The compliance of towering kerchief is between bight cap and sunglow hat. We can gain a conclusion that towering kerchief is one kind of high ranking noble men's hat styles as the Tsenpos and some other nobles wear towering kerchiefs in pictures funded in Lhasa.
5. Pigtails
The pigtails in pictures of Dunhuang grottoes and wooden coffins in Qinghai have the same style, the difference between them only lie in the place of its tip. According to the picture in NO. 231 grotto, Tibetans usually part their hair in forehead, then make these two beams of hair pigtails and tie a knot behind the head. According to the portrait of Tsenpo and his guards,Tibetans usually use jeweled rope to fix pigtails and reveal the tip of left pigtail on the right.
6. Red face painting
It is recorded by historical document that Tibetans have a customer to paint their face red, which is believed to originate from the animal sacrifice of Bonpo. We can find some evidence of red face painting on wooden coffins in Qinghai as dozens of people inthe picture paint their face red, they use red pigment to draw different kinds of red punctations on their faces, This kind of makeup is a endemic style of Tibet and also affect the makeup styles of Tangut kingdom (1038-1227). A painting drew by Wu Yuanzhi (a famous painter lived during 10th century and 11th century) showed a goddess who has the same makeup with the Tibetans in the pictures of Qinghai wooden coffins (《星宿神》 The English name of this painting is Star gods, which is unearthed in Kharar-khoto and collected in State Hermitage)
