Perhaps you should try some spelling variations:
manh thanh » danh thanh, minh thanh, manh thang
thanh tai » thanh hai, thanh toan, doanh tai
su sach » vu sach
tai cuu » tai cuc, tai buu, tai cua
cuu tre » cua tre, cau tren, cau treo
nang xa » nang x, lang xa, nang ma
so sach » so sanh, bo sach, co sach
ve cac » va cac, vien cac
ve cai » va cai, ve tai, ve cau

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: ((su sach) OR (so sach)) ky nang xa hoi. hieu ((ve cai) OR (ve cac)) suc manh thanh tai cuu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (so sach)) ky nang xa hoi. hieu ((ve cai) or (ve cac)) suc manh thanh tai cuu tre~".
• Adding a wildcard symbol may retrieve word variants: ((su sach) OR (so sach)) ky nang xa hoi. hieu ((ve cai) or (ve cac)) suc manh thanh tai cuu tre*.
