Perhaps you should try some spelling variations:
nang mai » nang ma, lang mai, nang cai
nang tai » hang tai, tang tai, sang tai
ban hanh » ban hang
ve cham » ve chat, vu cham, ve chim
va cham » va chat, va tham
xuc ban » duc ban, cuc ban, quoc ban
cuu tre » cua tre, cau tren, cau treo
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: tu cac ky ((nang mai) OR (nang tai)) hoi. hieu ((ve cham) or (va cham)) xuc ban hanh vi cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky ((nang mai) OR (nang tai)) hoi. hieu ((ve cham) OR (va cham)) xuc ban hanh vi cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky ((nang mai) OR (nang tai)) hoi. hieu ((ve cham) or (va cham)) xuc ban hanh vi cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu cac ky ((nang mai) OR (nang tai)) hoi. hieu ((ve cham) or (va cham)) xuc ban hanh vi cuu tre*.
