Perhaps you should try some spelling variations:
hanh dai » hanh tai, hanh dao, vanh dai
te sach » toc sach
sang xa » song xa, lang xa, mang xa
sang ma » tang ma, nang ma, sang tao
hieu ve » hieu va, hieu van
xuc van » luc van, vuc van, xuc ban
duc van » duc va, duc tan, duc manh
ve cac » va cac, vien cac
cua cu » cua chu, cua cau, cua 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 ((sang xa) OR (sang ma)) hoi. hieu ve cac ((xuc van) or (duc van)) hanh dai cua cu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y ((sang xa) OR (sang ma)) hoi. hieu ve cac ((xuc van) OR (duc van)) hanh dai cua cu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((sang xa) OR (sang ma)) hoi. hieu ve cac ((xuc van) or (duc van)) hanh dai cua cu*".
