The largest Lerentang head office? Does it mean flagship store? The one in Northland? Take bus 106 from the southern suburbs and get off at Northland Mall. You should stop at Jianhua South Street (west of Book Building), then cross the intersection and go straight along Zhongshan Road (north) to find a flagship store.

For western medicine, go to Xinxing Pharmacy. There are many chain stores, the price is reasonable, and there are discounts on membership day, which is very good!

There should be many Lerentang.
