Perhaps you should try some spelling variations:
lam truoc » lam thuoc, nam truoc, lam truong
va thanh » gia thanh, ban thanh, le thanh
cau treo » cau theo, cau tren, cau triet
sinh ty » sinh ly, sinh y, sinh tu
ty nang » ky nang, ty xang, ty hang
nang xa » nang x, lang xa, nang ma
va hanh » van hanh, va danh, ban hanh
va tinh » may tinh
va lam » van lam, va lap
vi cau » va cau, ve cau, di cau

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 ty nang xa hoi. lieu va lam truoc ((va hanh) or (((va thanh) OR (va tinh)))) vi cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc sinh ty nang xa hoi. lieu va lam truoc ((va hanh) OR (((va thanh) OR (va tinh)))) vi cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc sinh ty nang xa hoi. lieu va lam truoc ((va hanh) or (((va thanh) OR (va tinh)))) vi cau treo".
• Adding a wildcard symbol may retrieve word variants: hoc sinh ty nang xa hoi. lieu va lam truoc ((va hanh) or (((va thanh) OR (va tinh)))) vi cau treo*.
