Perhaps you should try some spelling variations:
cham cuu » cap cuu, chat cua
ve doanh » va doanh, de doanh, te doanh
thu sai » thu hai, thu san, thu ai
thu tai » tu tai, tru tai, thu hai
hieu vu » hieu ve, hieu su, dieu vu
hieu va » lieu va, hieu qua
cuc tre » duc tre, cua tre, cuu tre
cuu ve » cuu va
x hoi » xa hoi, o hoi, x ho

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: ((thu sai) OR (thu tai)) ky nang x hoi. ((hieu vu) OR (hieu va)) cham cuu ve doanh tai cuc tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sai) OR (thu tai)) ky nang x hoi. ((hieu vu) or (hieu va)) cham cuu ve doanh tai cuc tre~".
• Adding a wildcard symbol may retrieve word variants: ((thu sai) OR (thu tai)) ky nang x hoi. ((hieu vu) or (hieu va)) cham cuu ve doanh tai cuc tre*.
