y hoang » x hoang, _ hoang, m hoang
hieu va » lieu va, hieu qua
va cham » va chat, va tham
truc va » thuc va, trung va
vi cua » vai cua, di cua

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: "tu sach y hoang xa hoi. hieu va cham ((truc va) OR (thuc vat)) hanh vi cua te~".
• Adding a wildcard symbol may retrieve word variants: tu sach y hoang xa hoi. hieu va cham ((truc va) OR (thuc vat)) hanh vi cua te*.
