Perhaps you should try some spelling variations:
va thanh » gia thanh, ban thanh, va tinh
hieu van » hieu va, thien van, lieu va
te sach » toc sach
va hanh » van hanh, va danh, ban hanh
van cam » van nam, van lam, van cau
xu tren » tu tren, cu tren, xa tren
y nang » ky nang, ly nang, may nang
v nang » va nang, vu nang, van nang
vi xu » va xu, ve xu, vi su

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((y nang) OR (v nang)) xa hoi. hieu van cam xuc ((va hanh) or (va thanh)) vi xu tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((y nang) OR (v nang)) xa hoi. hieu van cam xuc ((va hanh) OR (va thanh)) vi xu tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((y nang) OR (v nang)) xa hoi. hieu van cam xuc ((va hanh) or (va thanh)) vi xu tren".
• Adding a wildcard symbol may retrieve word variants: te sach ((y nang) OR (v nang)) xa hoi. hieu van cam xuc ((va hanh) or (va thanh)) vi xu tren*.
