It's recommended to reduce time spent outside if you are feeling symptoms such as difficulty breathing or throat irritation.\n\nOverall, it's a pleasant and dry spring day in Beijing, though air quality is a concern. You may want to dress in layers, as it will feel cooler in the morning and evening, with comfortable and pleasant conditions in the afternoon.",
