vu khanh » vu thanh, van khanh, duy khanh
cua tre » cua te, cuu tre, cua triet
xuc van » duc van, luc van, vuc van
dan cua » dan ca, ban cua, dai cua
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
tu sac » tu sach, tu san, tu bac

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sac) or (tu cac)) ky lang xa hoi. hieu ((vu kham) OR (vu khanh)) xuc van thanh dan cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sac) OR (tu cac)) ky lang xa hoi. hieu ((vu kham) OR (vu khanh)) xuc van thanh dan cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sac) or (tu cac)) ky lang xa hoi. hieu ((vu kham) OR (vu khanh)) xuc van thanh dan cua tre".
• Adding a wildcard symbol may retrieve word variants: ((tu sac) or (tu cac)) ky lang xa hoi. hieu ((vu kham) OR (vu khanh)) xuc van thanh dan cua tre*.
