Perhaps you should try some spelling variations:
hanh tinh » hanh trinh, nhanh tinh, thanh tinh
tinh cuu » trinh cuu, dinh cuu, tinh cua
te sach » toc sach
sach ty » sach y, sach tu, sach thu
cuu tre » cua tre, cau tren, cau treo
ve chat » va chat, van chat
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma
ty nang » ky nang, ty xang, ty hang
tuc va » thuc va, truc va, tuc xa
xuc va » duc va, luc va, xac va

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 ty nang xa hoi. hieu ve chat ((((xuc va) OR (tuc va))) or (thuc vat)) hanh tinh cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty nang xa hoi. hieu ve chat ((((xuc va) OR (tuc va))) OR (thuc vat)) hanh tinh cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty nang xa hoi. hieu ve chat ((((xuc va) OR (tuc va))) or (thuc vat)) hanh tinh cuu tre".
• Adding a wildcard symbol may retrieve word variants: te sach ty nang xa hoi. hieu ve chat ((((xuc va) OR (tuc va))) or (thuc vat)) hanh tinh cuu tre*.
