Connecting Flight. I am a Filipina who were a Aupair in Denmark with a contract for 2 years.

I have a residence Visa here in Denmark. I live here with my host family for 1 year and 5 months. I will be having my vacation to visit my family on December 2018. That's for 3 weeks. My flight will be from Copenhagen to Amsterdam and Amsterdam to Xiamen, and Xiamen to Manila. That's Vise Versa. My question is, I have a layover of 11hrs at Xiamen. Do I have to get a Visa?
