Perhaps you should try some spelling variations:
thuong thong » thong thong, thuong trong, thuong phuong
thanh trung » thanh tung
cua thuong » cua truong, cua phuong, ca thuong
hien danh » thien danh, hien hanh, hien nhanh
trung cua » truong cua, trung tuan, trung cap
thong dan » thong van, tuong dan, thong den
phan cau » phan dau, phan tu, phan lap
phan cac » nhan cach, phan dau, phan lap

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: "hoc hien danh - thanh trung cua thuong thong dan ((phan cau) OR (phan cac))~".
• Adding a wildcard symbol may retrieve word variants: hoc hien danh - thanh trung cua thuong thong dan ((phan cau) OR (phan cac))*.
