Just like Rosh Hashanah, I spent Yom Kippur with Chabad in Shanghai but this time services were held in the Ohel Rachel Synagogue which is the  last standing synagogue in Shanghai still in use (limited use since the Chinese Government only allows Chabad to use the Synagogue a couple times throughout the year).  

Ohel Rachel was founded in 1920  and was the synagogue for three waves of Jews, first Baghdadi, then Russian, and later European; until the the war ended in 1945 and the founding of the PRC in 1949.

During the pre-fast meal I sat with a couple from Israel who moved here for work and have raised two kids that can speak both Chinese and Hebrew.  Moshe (the husband) said that their older daughter sometimes mixes Chinese with Hebrew and will say  我要 מים, I want water.
