Perhaps you should try some spelling variations:
doanh van » doan van, doanh va, doanh ban
va doanh » van doanh, vay doanh, va danh
van cua » vang cua, ban cua, dan cua
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
sach ky » sac ky, sach ty, sach kem
cam duc » cao duc, pham duc, nam duoc
cua te » cua tu

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ky) OR (sach y)) nang xa hoi. hieu va ((cam duc) or (cam xuc)) va doanh van cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sach y)) nang xa hoi. hieu va ((cam duc) OR (cam xuc)) va doanh van cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) OR (sach y)) nang xa hoi. hieu va ((cam duc) or (cam xuc)) va doanh van cua te*".
