Perils of the "Information Age". People can spontaneously seek out half or a dozen forums, join them all, and ask the same question over and over. Because they're not really "serious" about joining these forums and just "want an answer now" (probably because they didn't like what they already read when searching google). Again, when they don't like what they hear, they may never reply back. OR, they might not even remember where they posted, what username and password (or even email) they've used, and so on. The only bonsai trees sold at an age as a type of legitimization tag are mallsai. Reputable dealers can sometimes tell you the age of a tree, but not always, or sometimes in just "abouts".
So, yeah, I can almost guarantee it's a mallsai, but to the species, who knows. Juniper is a good guess, but then so is Fukien Tea, Serissa, or Elm. Doubtless, it's been kept inside, but that looks to be something we'll never have confirmed.
On another note, this being an English speaking forum and the original poster obviously not being a native speaker, perhaps she has found another forum where she can converse comfortably in her native tongue. If so, kudos to her.
