Perhaps you should try some spelling variations:
dieu hien » dieu khien, dieu kien, bieu hien
kinh vai » kinh hai, kinh va, kinh van
te sach » toc sach
vai cuu » vai cua
va kinh » va tinh, qua kinh
sach ky » sac ky, sach y, sach ty
cac lao » cac loai, cac giao, cac lang
cuu tre » cua tre, cau tren, cau treo
nang xa » lang xa, nang ma, mang xa
ca lao » cua lao, ca dao, ca cao

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((nang xa) OR (nang x)) hoi. dieu hien ((cac lao) OR (ca lao)) va kinh vai cuu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((nang xa) OR (nang x)) hoi. dieu hien ((cac lao) or (ca lao)) va kinh vai cuu tre~".
• Adding a wildcard symbol may retrieve word variants: te sach ky ((nang xa) OR (nang x)) hoi. dieu hien ((cac lao) or (ca lao)) va kinh vai cuu tre*.
