I'm not sure about this, but I like Ferriero very much. It's also famous. Italian Ferriero Group is the fourth largest chocolate manufacturer in the world, with a series of high-quality innovative products. Ferriero Kym is a world-famous brand.
There is also Degas Bora, the oldest and most famous royal chocolate brand in France.
Of course, N and Dove, which we are all familiar with, will be the most famous and largest seller in China ~ ~ ~
