Perhaps you should try some spelling variations:
tu sach » thu sach, su sach, te sach
hang di » hang doi, hang vi, hang dien
va hang » van hang, va nang, va lang
vu nang » vuc nang, va nang, vu dang
truc va » thuc va, thuc vat, trung va
di cua » dai cua, doi cua, de cua
ve tai » te tai, de tai, le tai
v nang » va nang, van nang, voi nang
cua te » cua tu

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: tu sach ((v nang) OR (vu nang)) xa hoi. hieu ((ve tai) OR (va cac)) truc va hang di cua te~.
• Adding a wildcard symbol may retrieve word variants: tu sach ((v nang) or (vu nang)) xa hoi. hieu ((ve tai) or (va cac)) truc va hang di cua te*.
