Perhaps you should try some spelling variations:
thuong nganh » trong nganh, thuong ngay, thuong gap
cong thuong » hang thuong
nganh thanh » nhanh thanh, danh thanh, nhanh thang
chieu tinh » trieu tinh, lieu tinh, chau tinh
thanh chau » thanh cha, thanh cham, thanh chu
trung cap » truong cao, trung tam
trung ha » trung hoc, trung tam
ha tinh » va tinh, may tinh

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

• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu tinh) OR (ha tinh)) - hanh ((trung ha) OR (trung cap)) cong thuong nganh thanh chau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu tinh) or (ha tinh)) - hanh ((trung ha) OR (trung cap)) cong thuong nganh thanh chau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu tinh) or (ha tinh)) - hanh ((trung ha) OR (trung cap)) cong thuong nganh thanh chau*.
