中国自主品牌博览会将开幕 上海老字号推介国货精品 - 2019年05月10日

They are laozihao, or “time-honored” brands” — some of which are centuries old and from a time before phones, let alone computers  — and now they’re riding the Internet wave.
They will have their presence at the second Exposition on China Indigenous Brands to be held from Friday to Sunday in Shanghai Exhibition Center.
One of the products is zongzi, with some laozihao teaming up with new platforms to find new selling points as China heads into the June 7 Dragon Boat festival.
