Rongshida and Hefei Rongshida are the same company?

No, Rongshida is a manufacturer of diversified products such as washing machines and refrigerators, while Hefei Rongshida Electrician Co., Ltd. is an electrician company that mainly produces cables. Royalstar is a famous brand and trademark in China, and once ranked 54th in the list of the most valuable well-known trademarks in China. Hefei Rongshida Sanyo Electric Co., Ltd. was once a subsidiary of Hefei Rongshida Group, so Rongshida and Hefei Rongshida are not the same company.
