Perhaps you should try some spelling variations:
phat thanh » pham thanh, phan thanh, ha thanh
phat hanh » nhat hanh, pham hanh, pham thanh
pham duy » pham duc
cuc tre » duc tre, cua tre, cuu tre
ve pham » vi pham, v pham, ve phan
hieu ve » hieu va, hieu van
lang xa » lang ha, dang xay, lang van
dang xa » dang xay, dang ha, dang va
tai ky » thai ky, trai ky, sai ky
su tai » su thi, tu tai

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

• Performing a fuzzy search may retrieve terms with similar spellings: su tai ky ((dang xa) or (lang xa)) hoi. hieu ve pham duy ((phat hanh) OR (phat thanh)) tai cuc tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su tai ky ((dang xa) OR (lang xa)) hoi. hieu ve pham duy ((phat hanh) OR (phat thanh)) tai cuc tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su tai ky ((dang xa) or (lang xa)) hoi. hieu ve pham duy ((phat hanh) OR (phat thanh)) tai cuc tre*".
