Perhaps you should try some spelling variations:
ban hanh » ban hang
nang mai » nang ma, nang tai, lang mai
cham xuc » cam xuc, chat xuc, cham soc
tu sach » thu sach, su sach, te sach
hieu va » lieu va, hieu qua
hanh di » hanh vi, hanh de, hang di
xuc ban » duc ban, cuc ban, quoc ban
cua tuc » cua duc, cua tu, cua thuoc
hieu ve » hieu van
mai hoi » mai khoi, dai hoi, lai hoi
y nang » ky nang, ly nang, v nang
di cua » dai cua, doi cua, de cua

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: ((tu sach) OR (thu hoach)) y nang mai hoi. ((hieu ve) OR (hieu va)) cham xuc ban hanh di cua tuc~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (thu hoach)) y nang mai hoi. ((hieu ve) OR (hieu va)) cham xuc ban hanh di cua tuc~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (thu hoach)) y nang mai hoi. ((hieu ve) OR (hieu va)) cham xuc ban hanh di cua tuc*.
