Perhaps you should try some spelling variations:
nang xa » lang xa, nang ma, mang xa
va hanh » van hanh, va thanh, va danh
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
ve cai » va cai, ve cac, ve tai
va cam » va cham, va cac, va cao
thu va » thuc va, thue va, tu va
vi cua » vai cua, di cua

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 (nang x)) hoi. hieu ((ve cai) OR (va cam)) thu va hanh vi cua vat~.
• Adding a wildcard symbol may retrieve word variants: tu sac ky ((nang xa) or (nang x)) hoi. hieu ((ve cai) or (va cam)) thu va hanh vi cua vat*.
