Perhaps you should try some spelling variations:
thien van » thi van
cau tren » cu tren, dau tren, ca tren
ban hang » ngan hang
va thanh » gia thanh, ban thanh, va tinh
cham xuc » cam xuc, chat xuc, cham soc
van cham » van chat, van tham, va cham
sach ty » sach y, sach tu, sach thu
ty nang » ky nang, ty xang, ty hang
vai cau » va cau, van cau, vai cac
tu sach » thu sach, su sach, te sach
x hoi » xa hoi, o hoi, x ho

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 ty nang x hoi. thien van cham xuc ((((ban hanh) OR (ban hang))) or (va thanh)) vai cau tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty nang x hoi. thien van cham xuc ((((ban hanh) OR (ban hang))) OR (va thanh)) vai cau tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty nang x hoi. thien van cham xuc ((((ban hanh) OR (ban hang))) or (va thanh)) vai cau tren".
• Adding a wildcard symbol may retrieve word variants: tu sach ty nang x hoi. thien van cham xuc ((((ban hanh) OR (ban hang))) or (va thanh)) vai cau tren*.
