Perhaps you should try some spelling variations:
thieu nien » thien nhien
thanh tai » thanh hai, thanh toan, doanh tai
cac truc » cau truc, cac trung, sach truc
thu sach » thuat sach, thuoc sach, thu hoach
va thanh » gia thanh, ban thanh, va tinh
cac tru » ca tru, cac tro, cac thu
tai cua » thai cua, tai cuc, tri cua
tu sach » su sach, te sach, tu cach
nang xa » nang x, lang xa, nang ma
cua te » cua tu

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: ((tu sach) OR (thu sach)) ky nang xa hoi. thieu nien ((cac truc) OR (cac tru)) va thanh tai cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (thu sach)) ky nang xa hoi. thieu nien ((cac truc) OR (cac tru)) va thanh tai cua te~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (thu sach)) ky nang xa hoi. thieu nien ((cac truc) OR (cac tru)) va thanh tai cua te*.
