Perhaps you should try some spelling variations:
muong dong » muong doong, muong duong, tuong dong
thien van » thi van
xa muong » ca muong, xa truong, xa dong
van cam » van nam, van lam, van cau
cua tre » cuu tre, cua triet, dua tren
cam tuc » cam xuc, cam tu, nam thuc
so sanh » do sanh
sanh ky » hanh ky, sang ky, nganh ky
nang ma » tang ma, sang ma, nang cao
nang xa » nang x, lang xa, mang xa
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: so sanh ky ((nang xa) or (nang ma)) hoi. thien van cam tuc xa muong dong ((cua tre) OR (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sanh ky ((nang xa) OR (nang ma)) hoi. thien van cam tuc xa muong dong ((cua tre) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sanh ky ((nang xa) or (nang ma)) hoi. thien van cam tuc xa muong dong ((cua tre) OR (cua te))*".
