Perhaps you should try some spelling variations:
tieu tinh » trieu tinh, tieu trinh, lieu tinh
trang cua » tranh cua, tang cua, thang cua
trung cua » truong cua, trung tuan, trung cap
dung cong » dung trong
cong manh » cong danh, duong manh, cong thanh
manh toan » thanh toan, anh tuan, tinh toan
toan cau » toan cao, toan ban, toan tap

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: "theo tieu tinh - hanh ((trang cua) OR (trung cua)) dung cong manh toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo tieu tinh - hanh ((trang cua) OR (trung cua)) dung cong manh toan cau*.
