Perhaps you should try some spelling variations:
thieu lang » thieu khang, thieu quang, chieu sang
truong cua » truong ca, truong quan, truong cao
hieu lang » chieu sang, hieu quang, nhieu tang
trung cap » truong cao, trung tam
hang cong » dang cong, hang nong, bang cong
cong anh » cong danh, dong anh, hong anh
tuan cu » tuan tu, quan cua, tuan thu

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: hoc ((thieu lang) OR (hieu lang)) - hanh ((trung cap) OR (truong cua)) hang cong anh tuan cu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu lang) OR (hieu lang)) - hanh ((trung cap) or (truong cua)) hang cong anh tuan cu~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu lang) OR (hieu lang)) - hanh ((trung cap) or (truong cua)) hang cong anh tuan cu*.
