Perhaps you should try some spelling variations:
nhung tuong » nhung huong, nhung phuong, hung vuong
chieu sang » chieu sach, chieu xanh, hieu lang
chinh han » chinh phan, chin han, chinh ban
han nhung » hanh nhung, hon nhung, ban nhung
tuong dan » huong dan, tung dan, xuong dan
phan tap » phan lap, han tap, phan tu
pha tap » pham tai

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: doi ((chieu sang) OR (trieu tinh)) - hanh chinh han nhung tuong dan ((phan tap) OR (pha tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu sang) or (trieu tinh)) - hanh chinh han nhung tuong dan ((phan tap) OR (pha tap))~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu sang) or (trieu tinh)) - hanh chinh han nhung tuong dan ((phan tap) OR (pha tap))*.
