Perhaps you should try some spelling variations:
thieu khang » chieu khong, thieu quang
hanh trung » thanh trung, hanh trang, manh trung
hoc thieu » toc thieu, hoc hien
trung dai » truong dai, truong dao, trung tam
cong manh » duong manh, cong thanh, hoang manh
cong danh » cuong danh, cong dan, cong thanh
toan cau » toan ban, toan tap, toan tai
toan cao » toan ban, toan tap
dai ung » dap ung, dan ung, di ung

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 khang - hanh trung dai ung ((cong manh) OR (cong danh)) ((toan cau) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu khang - hanh trung dai ung ((cong manh) OR (cong danh)) ((toan cau) or (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu khang - hanh trung dai ung ((cong manh) OR (cong danh)) ((toan cau) or (toan cao))*.
