If your main goal is treatment, then I would recommend that you still consider Dalian if the quality beach rest, then Hainan . In Baidah very few people are treated, mostly there go to the sea, which is much inferior to the resorts of the South China Sea . If for any reason you plan your trip exclusively in Baidah and want to always combine beach rest with health procedures, attention to the three-star "Heilongjis Labor High School Sanatorium (200 m from the sea, the price includes three meals a day, acupuncture, foot massage) .
