there is no difference, they are the same company.

Laoxiang Chicken originated from a local catering company in Hefei. As a Hefei person, it has grown from only a few stores to all over the street. There is a saying in Hefei that Feidong bought an old hen in Feixi, which shows that Feixi's old hen is particularly good. As for why Feixi's old hen changed its name to Laoxiang Chicken, it is rumored that Feidong people registered Feixi's old hen with the company, which caused Feixi's old hen to change its name after opening many stores.
