Perhaps you should try some spelling variations:
sinh lam » dinh lam, sinh ly, sinh vat
lam cua » nam cua, lam chat
va sinh » va kinh, va tinh, vi sinh
sach ky » sach y, sach ty, sach kem
cua tre » cua te, cuu tre, cua triet
sang xa » song xa, lang xa, sang ma
ve cac » va cac, vien cac
sac ky » cac ky, sai ky
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: te ((sach ky) OR (sac ky)) sang xa hoi. hieu ((ve cam) or (ve cac)) duc va sinh lam cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sac ky)) sang xa hoi. hieu ((ve cam) OR (ve cac)) duc va sinh lam cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) OR (sac ky)) sang xa hoi. hieu ((ve cam) or (ve cac)) duc va sinh lam cua tre*".
