Perhaps you should try some spelling variations:
lieu tinh » trieu tinh, diep tinh, bien tinh
nang hang » nang sang, hang hang, cang thang
duong van » duong va, luong va, dang van
thanh tap » thanh lap, thanh tai, thanh tam
thanh tay » thanh tai, thanh toan, thanh thuy
doi lieu » duoc lieu, doi chieu, du lieu
va dong » van dong, xa dong, lao dong
ha dong » hoat dong, van dong

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 lieu tinh - nang hang ((va dong) OR (ha dong)) duong van ((thanh tap) OR (thanh tay))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi lieu tinh - nang hang ((va dong) or (ha dong)) duong van ((thanh tap) OR (thanh tay))~".
• Adding a wildcard symbol may retrieve word variants: doi lieu tinh - nang hang ((va dong) or (ha dong)) duong van ((thanh tap) OR (thanh tay))*.
