Perhaps you should try some spelling variations:
sinh ky » sinh ly, sinh y, minh ky
va dinh » van dinh, va kinh, va tinh
va danh » va dan, va hanh, dia danh
ca tren » cau tren, cu tren, la tren
hieu ve » hieu va, hieu van
lang xa » lang ha, dang xay, lang van
kinh ky » minh ky, trinh ky, kinh tay
ve cau » ke cau, va cau, ve cac
vi ca » vit ca, li ca, va ca

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

• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((sinh ky) OR (kinh ky)) lang xa hoi. hieu ve cau truc ((va danh) or (va dinh)) vi ca tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((sinh ky) OR (kinh ky)) lang xa hoi. hieu ve cau truc ((va danh) OR (va dinh)) vi ca tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((sinh ky) OR (kinh ky)) lang xa hoi. hieu ve cau truc ((va danh) or (va dinh)) vi ca tren".
• Adding a wildcard symbol may retrieve word variants: hoc ((sinh ky) OR (kinh ky)) lang xa hoi. hieu ve cau truc ((va danh) or (va dinh)) vi ca tren*.
