Perhaps you should try some spelling variations:
va thanh » gia thanh, ban thanh
cau tren » cu tren, dau tren, ca tren
vu sach » vu bach, su sach, vu khach
sach tu » sach thu, cach tu, sach ty
tu nang » tru nang, tu nong, tu nano
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
va tinh » may tinh
ve cam » ve cham, ve cac, va cam
ve cau » ke cau, va cau, ve cac

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: vu sach tu nang xa hoi. hieu ve cam xuc ((((va thanh) OR (le thanh))) OR (va tinh)) ve cau tren~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach tu nang xa hoi. hieu ve cam xuc ((((va thanh) OR (le thanh))) or (va tinh)) ve cau tren~".
• Adding a wildcard symbol may retrieve word variants: vu sach tu nang xa hoi. hieu ve cam xuc ((((va thanh) OR (le thanh))) or (va tinh)) ve cau tren*.
