五一假期反季促销海报设计：内蒙古大草原与集宁国际皮革城

我是一名企业策划，想要画一张活动宣传海报，里面元素要突出'五一假期 反季促销'汉字内容，要有内蒙古大草原，要有集宁国际皮革城，整个画风要惬意，要舒适。

I am a business planner and would like to create a promotional poster for the upcoming May Day holiday, featuring the theme of 'Off-season Promotion'. The poster should include elements such as the vast Inner Mongolian grasslands and the Jining International Leather City, and the overall style should be relaxed and comfortable.
