Perhaps you should try some spelling variations:
phuong dong » phuong dung, phuong hoang, chuong duong
phuong doi » huong doi, phuong doan, phuong troi
so sach » so sanh, bo sach, co sach
sach ky » sac ky, sach y, sach ty
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
va cam » va cham, va cac, va cao
xuc xa » tuc xa, buc xa
cua tu » cua tuc, cua su, cua cu

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

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