This is a post from Andrea Nguyen. the one on the right is stocked by 99 Ranch Mt View, so its likely available in other 99 Ranches. I believe you can get 8 year, 10 year, 15 year Gu Yue Long Shan 古越龍山 huadiao online for sure. Though someone may know whether places in Oakland Chinatown stocks them. 10, 15 year is a bit overkill for chicken though.
