Perhaps you should try some spelling variations:
trong manh » trong minh, trong anh, trong mach
truong anh » trong anh, trung anh, truong thanh
chai tinh » chau tinh, thai tinh, cham tinh
doi chai » doi chi, doi thoai, doi cua
trang va » tran van, hang va
toan cao » toan ban, toan tap
tan van » tran van, tang van, luan van

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: doi chai tinh - canh ((trang va) OR (tan van)) dung ((trong manh) OR (truong anh)) toan cao~.
• Adding a wildcard symbol may retrieve word variants: doi chai tinh - canh ((trang va) or (tan van)) dung ((trong manh) or (truong anh)) toan cao*.
