Is Kantaro a brand of Guangwei?

No, Kantaro and Guangwei are two brands of fishing gear. According to Tian Yan's inquiry, Hantailong is a brand of Shandong Weihai and belongs to Weihai Hantailong Fishing Gear Co., Ltd. Although Guangwei is also a brand of Weihai, it belongs to Weihai Guangwei Group Co., Ltd. Both Hantailong and Guangwei have their own companies and patents, so Hantailong is not a brand of Guangwei.
