Perhaps you should try some spelling variations:
danh vai » danh sai, danh va, doanh van
thu dac » thu duc, thu xac, thu da
thu san » thuy san, thu ban, phu san
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
vai cuu » vai cua
cuu tre » cua tre, cau tren, cau treo
lao va » cao va, bao va, dao va

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((thu dac) or (thu san)) ky nang xa hoi. hieu va cac ((lao va) OR (tao va)) danh vai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu dac) OR (thu san)) ky nang xa hoi. hieu va cac ((lao va) OR (tao va)) danh vai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu dac) or (thu san)) ky nang xa hoi. hieu va cac ((lao va) OR (tao va)) danh vai cuu tre".
• Adding a wildcard symbol may retrieve word variants: ((thu dac) or (thu san)) ky nang xa hoi. hieu va cac ((lao va) OR (tao va)) danh vai cuu tre*.
