On a hill, the only immediate one of Qingshi ; a short while, Qingshi into smoke plume, rising Madadayo; then also formed around Qingyun, rain, Cai-feng, crane fly the mountain valleys in between ...... Yu are wondering, Yao Ji touching beauty suddenly appeared before him.

上得山来，只见眼前一块婷婷玉立的青石；不一会，青石化为一缕青烟，袅袅升起；继而又形成团团青云，霏霏细雨，游龙、彩凤、白鹤飞翔于山峦峡谷之间……夏禹正在纳闷，美丽动人的瑶姬突然出现在他面前。

It may also comes from the old term dichroite, also a Greek term which means "two-colored rock", in reference with the strong characteristic of cordierite's pleochroism.

它也来了，从旧的术语堇青石也是希腊文的意思是"两色的石头"在提到，在堇青石的多色性强的特点。

In this paper,the Raman spectrum were used to study sapphire,dichroite,aquamarinl,topaz and kyanite,it is found that the characteristic Raman translocations of sapphire which are caused by Al-O vibration are 413cm-1,640cm-1 and 668cm-1,the characteristic Raman translocations of dichroite which are caused by Si-O vibration are 550cm-1,662cm-1,964cm-1and 1176cm-1,the characteris.
