Perhaps you should try some spelling variations:
van thanh » ban thanh, van tuan
tang mai » tang ma, tang tai, lang mai
thanh do » thanh de, thanh pho, thanh hoa
tu sach » thu sach, su sach, te sach
mai hoi » mai khoi, dai hoi, lai hoi
va cham » va chat, va tham
xuc van » duc van, luc van, vuc van
y tang » ky tang, 6 tang, 7 tang
ve cam » ve cham, ve cac, va cam
do cua » doi cua, co cua, de cua

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 y tang mai hoi. hieu ((ve cam) OR (va cham)) xuc van thanh do cua vat~.
• Adding a wildcard symbol may retrieve word variants: tu sach y tang mai hoi. hieu ((ve cam) or (va cham)) xuc van thanh do cua vat*.
