Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
van thanh » ban thanh, van tuan
may nong » may cong, may nang, mo nong
tu sach » thu sach, su sach, te sach
vai cua » dai cua, hai cua, lai cua
xuc van » duc van, luc van, vuc van
cua duc » cua tuc, cua nuoc, cua quoc
mai hoi » mai khoi, dai hoi, lai hoi
va cao » va cac, va co, va dao
v nang » va nang, vu nang, van nang
va cam » va cham, va cac, va cai

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ((may nong) or (v nang)) mai hoi. lieu ((va cam) OR (va cao)) xuc van thanh vai cua duc~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((may nong) OR (v nang)) mai hoi. lieu ((va cam) OR (va cao)) xuc van thanh vai cua duc*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((may nong) or (v nang)) mai hoi. lieu ((va cam) OR (va cao)) xuc van thanh vai cua duc*".
