Perhaps you should try some spelling variations:
hanh vai » hanh vi, hanh va, hanh tai
sang tao » hang tai
van hanh » van thanh, ban hanh, van anh
vai cuu » vai cua
duc van » duc va, duc tan, duc manh
cuu tre » cua tre, cau tren, cau treo
sang ma » tang ma, nang ma, mang may
ve cac » va cac, vien cac
ve cam » ve cham, va cam, ve 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 cac ky ((sang ma) OR (sang tao)) hoi. hieu ((ve cam) or (ve cac)) duc van hanh vai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky ((sang ma) OR (sang tao)) hoi. hieu ((ve cam) OR (ve cac)) duc van hanh vai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky ((sang ma) OR (sang tao)) hoi. hieu ((ve cam) or (ve cac)) duc van hanh vai cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu cac ky ((sang ma) OR (sang tao)) hoi. hieu ((ve cam) or (ve cac)) duc van hanh vai cuu tre*.
