Perhaps you should try some spelling variations:
thanh doi » thanh loi, thanh moi, thanh do
xanh doi » xanh di, tinh doi, anh doc
ve cham » va cham, ve chat, vu cham
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma
cua tre » cua te, cuu tre, cua triet
sach v » sach va, sach y, sach vay
soc va » hoc va, loc va, doc va
sach 2 » sach y

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 v) or (sach 2)) nang xa hoi. hieu ve cham soc va ((xanh doi) OR (thanh doi)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach v) OR (sach 2)) nang xa hoi. hieu ve cham soc va ((xanh doi) OR (thanh doi)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach v) or (sach 2)) nang xa hoi. hieu ve cham soc va ((xanh doi) OR (thanh doi)) cua tre*".
