Perhaps you should try some spelling variations:
tham thong » pham thuong, than thuong, thoai thong
manh tuong » manh cuong, minh tuong, manh hung
thong cong » trong cong, tong cong, thong thong
hien xanh » hien hanh, hien nhanh, chieu xanh
manh tung » manh hung, thanh tung
cong tinh » cong trinh, cong vinh, long tinh
tinh van » trinh van, dinh van, tinh va

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

• Performing a fuzzy search may retrieve terms with similar spellings: hoc hien xanh - ((((manh tuong) OR (anh huong))) or (manh tung)) tham thong cong tinh van ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hien xanh - ((((manh tuong) OR (anh huong))) OR (manh tung)) tham thong cong tinh van ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien xanh - ((((manh tuong) OR (anh huong))) or (manh tung)) tham thong cong tinh van ban*".
