Perhaps you should try some spelling variations:
nam thuoc » nam thuc, nam thu, nha thuoc
va thanh » ban thanh, le thanh
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
va tinh » may tinh
vu hai » su hai, vu ha
hai ky » thai ky, hoi ky, hai ly
ve nam » he nam, va nam, le nam
vi cua » vai cua, di cua
cua cu » cua chu, cua cau, cua su

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

• Performing a fuzzy search may retrieve terms with similar spellings: vu hai ky nang xa hoi. hieu ve nam thuoc ((((va thanh) OR (va tinh))) or (gia thanh)) vi cua cu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu hai ky nang xa hoi. hieu ve nam thuoc ((((va thanh) OR (va tinh))) OR (gia thanh)) vi cua cu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu hai ky nang xa hoi. hieu ve nam thuoc ((((va thanh) OR (va tinh))) or (gia thanh)) vi cua cu*".
