Perhaps you should try some spelling variations:
va thanh » gia thanh, ban thanh, va tinh
sinh ty » sinh ly, sinh y, sinh tu
ty nang » ky nang, ty xang, ty hang
nang xa » nang x, lang xa, nang ma
van lam » van nam
va hanh » van hanh, va danh, ban hanh
cuu tre » cua tre, cau tren, cau treo
va lam » va lap
vi cuu » vi luu, vinh cuu

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