Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
nang mai » nang ma, nang tai, lang mai
va thanh » gia thanh, ban thanh, va tinh
hieu van » hieu va, thien van, lieu va
cuu tre » cua tre, cau tren, cau treo
cac bac » cac bai, cac ban, cac cach
vai cuu » vai cua
cac tac » cac toc, cac dac, cac tai
mai hoi » mai khoi, dai hoi, lai hoi
su cao » cu cao, vu cao, su co
su sac » su sach, su cac, su xac

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((su sac) or (su cao)) ky nang mai hoi. hieu van ((cac tac) OR (cac bac)) va thanh vai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sac) OR (su cao)) ky nang mai hoi. hieu van ((cac tac) OR (cac bac)) va thanh vai cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) or (su cao)) ky nang mai hoi. hieu van ((cac tac) OR (cac bac)) va thanh vai cuu tre*".
