Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
van thanh » ban thanh, van tuan
te sach » toc sach
vai cua » dai cua, hai cua, lai cua
duc van » duc va, duc tan, duc manh
ve cac » vien cac
y nang » ky nang, ly nang, may nang
v nang » va nang, vu nang, van nang
cua te » cua tu

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

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