I had the great fortune of serving a LDS mission in the Washington D.C. North Mission. At the time there was only our little Montgomery Chinese Branch which met in an old chapel in Potomac Maryland.
It was frustrating sometimes to meet someone who spoke mandarin chinese but lived in Virginia, which was outside our mission boundaries. The Washington D.C. South Mission at the time did not have Chinese speaking missionaries.
I am happy to finally see a branch formed in that area. KSL article. The Twin Lakes Chinese Branch will meet in Centreville, Virginia. It is very exciting to see the growth of the church in that area in providing chinese speaking members a place to hear the gospel in their native language.
