Perhaps you should try some spelling variations:
chat xuc » chat huu, cam xuc, chao xu
su sach » so sach, vu sach
sach ty » sach y, sach tu, sach thu
xang xa » lang xa, mang xa, ang xa
hai xuc » hai cuc, hai xu, hai huoc
va hanh » van hanh, va thanh, va danh
lai cua » dai cua, hai cua, lai chau
vi cua » vai cua, di cua

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sach ty xang xa hoi. hieu qua ((hai xuc) OR (chat xuc)) va hanh ((vi cua) or (lai cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty xang xa hoi. hieu qua ((hai xuc) OR (chat xuc)) va hanh ((vi cua) OR (lai cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty xang xa hoi. hieu qua ((hai xuc) OR (chat xuc)) va hanh ((vi cua) or (lai cua)) tre*".
