Perhaps you should try some spelling variations:
thanh dai » thanh hai, thanh tai, thanh dat
ve thanh » le thanh, de thanh, den thanh
su sach » so sach, vu sach
sach ty » sach y, sach tu, sach thu
vu cham » va cham, vu kham, tu cham
ve chat » va chat, van chat
ve cham » va cham, ve chim, viet cham
ty nang » ky nang, ty xang, ty hang
cuu ve » cuu va
cua te » cua tu
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sach ty nang x hoi. hieu ((((ve cham) OR (ve chat))) or (vu cham)) cuu ve thanh dai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty nang x hoi. hieu ((((ve cham) OR (ve chat))) OR (vu cham)) cuu ve thanh dai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty nang x hoi. hieu ((((ve cham) OR (ve chat))) or (vu cham)) cuu ve thanh dai cua te".
• Adding a wildcard symbol may retrieve word variants: su sach ty nang x hoi. hieu ((((ve cham) OR (ve chat))) or (vu cham)) cuu ve thanh dai cua te*.
