Adopted through Love the Children 1985

I was born 3/13/1985 and adopted through Love the Children. I came to the US July 27, 1985. I am looking for my birth parents and sibling(s), if any. I have no information and the agency has closed its door. I'm not sure where their records went when it closed. The only part of my korean name I am sure of is Ae Rim, surname is either Cheung or Jong. If anyone who has found their birth family has any tips on the search, I am very open to suggestions. Thank you =)
