Perhaps you should try some spelling variations:
thuong phuong » truong phuong, thong phuong, thong thuong
vat thuong » va thuong, van thuong, tat thuong
phuong van » phung van, phong van, phuong lan
doi chieu » doc hieu, doi chi, mot chieu
hanh sinh » hanh tinh, hanh dinh, hinh sinh
doi lieu » duoc lieu, du lieu, tai lieu
ban tap » bai tap, han tap, ban tai

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 lieu) OR (doi chieu)) tinh - hanh sinh vat thuong phuong van ban tap~.
• Adding a wildcard symbol may retrieve word variants: ((doi lieu) or (doi chieu)) tinh - hanh sinh vat thuong phuong van ban tap*.
