Perhaps you should try some spelling variations:
phuong thi » phung thi, phong thi, phuong thuc
huong thi » luong thi, duong thi, vuong thi
biet gian » viet giao, biet giua, bien gia
trong tan » trong quan, trong cac, trong ca
yen vang » yen lang, yen giang, nen van
tan than » tan thanh, tan tran, ban than

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((phuong thi) OR (huong thi)) yen vang. biet gian trong tan than~".
• Adding a wildcard symbol may retrieve word variants: ((phuong thi) OR (huong thi)) yen vang. biet gian trong tan than*.
