I would like to take this opportunity to tell you the end of Xu's story. The Chinese guy that my maths' teacher started to adopt some years ago with many difficulties, but fortunately everything turned out well in the end and now they are all together with their families and Xu is already in Spain with their parents.
After following the process and the time spending by the parents in China, I have to admit that it is a difficult process and it is needed a clear mind because I suppose that many feelings came to your mind but you have to know how to control yourself.
Now they have many things to tell and it is a different and I'm sure that when Xu grew up he will have many things to tell about his childhood, but he will never have any doubt that their parents have done more than the impossible to stay with him.
His parents now have plenty of things to tell, because they have had the possibility to know a country not as tourists but as native people, even though it could be an advantage, positive and negative aspects about that were included in the trip. It has been an experience that they will never forget.
