The first thing you have to take care about is that his itinerary is:
Italy or elsewhere in Europe - China (but, only one stop) - Hong Kong
This itinerary will allow him to enjoy 144 hour visa free transit in the Chinese city of his choice. Again, it is allowed to have only one stop within China!
After he has booked his tickets according to above instruction, he will print his flight tickets and have those printouts with himself. Also, he will declare in Europe that he will travel to Hong Kong via X city in China using 144 hour visa free transit. After a short inspection, he will be allowed to board the plane.
Upon arrival in a Chinese city of his choice, he will approach 144 hour visa free transit where he will fill out the blue form. Again, after a short waiting, he will get a sticker in his passport (everything is free of charge) and he will be allowed to exit the airport.
Basically, this is it.
