Perhaps you should try some spelling variations:
chua xang » chua nang, chuc nang, chu bang
huong cua » dung cua
dung cong » dung trong
cong tinh » cong trinh, cong vinh, long tinh
chu manh » ho manh, chu han, chu van
hang cua » mang cua, hang ca, thong cua
toan cau » toan cao, toan ban, toan tap

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: theo ((chu manh) OR (chua xang)) - thanh ((hang cua) OR (huong cua)) dung cong tinh toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu manh) or (chua xang)) - thanh ((hang cua) OR (huong cua)) dung cong tinh toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu manh) or (chua xang)) - thanh ((hang cua) OR (huong cua)) dung cong tinh toan cau*.
