Old China Rose. It was called 国色天香 in China with exceptional fragrant old rose scent. It could be eaten，sweet！quite yummy.
Not Fabvier. Additional information about this rose：
It blooms almost throughout the year from April to January.
Number of petals are always above 50 in spring，autumn and winter，but much fewer in summer. This may be the major difference between 国色天香 and Gruss an Tepliz.
It has a wide distribution in China. It could be eaten，made into rose jams with sugar and honey，applied in baking，tea，etc.
Maybe Gruss an Tepliz is the sister of 国色天香？They do resemble each other.
I collected four similar roses. Only one kind blooms in spring and summer. The other three keep blooming into midwinter in Shanghai.
I met this rose more than 20 years ago. The fragrance brought my childhood memory back.
