Perhaps you should try some spelling variations:
hanh vai » hanh vi, hanh va, hanh tai
vai cua » dai cua, hai cua, lai cua
va hanh » van hanh, va thanh, va danh
cao duc » dao duc, cao suc, giao duc
cau duc » cau luc, chu duc, cau truc
hieu va » lieu va, hieu qua
nang xa » nang x, lang xa, nang ma
lang ha » long ha
sac ky » cac ky, sai ky
tu sac » tu sach, tu cac, tu san

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 sac ky ((nang xa) OR (lang ha)) hoi. hieu va ((cau duc) OR (cao duc)) va hanh vai cua vat~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky ((nang xa) or (lang ha)) hoi. hieu va ((cau duc) OR (cao duc)) va hanh vai cua vat~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky ((nang xa) or (lang ha)) hoi. hieu va ((cau duc) OR (cao duc)) va hanh vai cua vat*.
