I have lived in Shenzhen for more than 20 years and I don&;t like it. ; I don&;t know any specialties. . . I think squab is a specialty, but you can; I can&;t take it away, so you can only eat here. A few years ago, there was a Shenzhen wine, but it was not famous, so it was not recommended. Others, I think electronic products may be regarded as Shenzhen specialties, haha! As for bacon, I can; I can not help you with anything. Take some photos and go back ~ make postcards, which is also a souvenir!
Hope to adopt!
