Old / important Matzu temple in Shih-lin?

I’m looking for a Matzu temple in Shih-lin, that other temples send (or used to send) their god-statues to visit, and that holds (or held) an annual da baibai for Matzu’s birthday. Apparently this was famous all over Shih-Lin, Danshui, and Guanyinshan. Anybody know what temple it could be?

Sounds like Cixian, 士林慈諴宮. Because of its age it would be a “mother temple” to many others. The god statues aren’t brought for a visit, but to restore their ling, or efficacious power.
