Perhaps you should try some spelling variations:
thanh li » thanh loi, thanh le, nhanh li
va thanh » gia thanh, ban thanh, va tinh
cu tren » tu tren, dua tren
ve cham » va cham, ve chat, vu cham
mai hoi » mai khoi, dai hoi, lai hoi
tuc va » thuc va, truc va, tuc xa
tu cam » tu cham, tu cac, tu nam
cam ky » cao ky, cac ky
ve cam » ve cac, va cam, ve cai
li cu » li ca, li du, le cu

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu cam ky nang ((le hoi) or (mai hoi)). hieu ((ve cam) OR (ve cham)) tuc va thanh li cu tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cam ky nang ((le hoi) OR (mai hoi)). hieu ((ve cam) OR (ve cham)) tuc va thanh li cu tren*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cam ky nang ((le hoi) or (mai hoi)). hieu ((ve cam) OR (ve cham)) tuc va thanh li cu tren*".
