The Beijing International Horticulture Expo is a good place to simply breathe and relax. According to a 2017 study, exposure to nature, like taking a walk through a garden, has positive health benefits, such as lowering depression and anxiety.

It is also a place to absorb different world cultures. Visitors can appreciate the aesthetics of many different countries in Beijing.

It's not only about the fun but the food: From German beer to Turkish coffee to French baguettes, you can get a taste of the world.

And for visitors who have limited knowledge of plants, there are many apps to help them become more informed.
