Hotel or other accommodation confirmation

In general, typical question in most countries, upon arrival of foreigner, is where will you stay. In other words, it is expected that a foreigner has accommodation booking for at least the first overnight regardless if this is a booking done for a group or for a single visitor. It is not necessary that your name appears at the booking confirmation if it is a group reservation or if the reservation is done by a third person. It is important that you will use the accommodation. However, if you decide to stay at your friends, relatives or similar, you can, of course, do that. In that case, you should prepare the following: identity of person where will you stay, her/his local phone number and precise address. This will be fine as far as the airport is concerned. When you arrive at your friend or relative, you will visit, best accompanied by your host, to the closest PSB (public security bureau) facility where you will perform a registration within 24 hours upon your arrival in China.

As far as your second segment is concerned, you can use 144 hour visa free transit as much as you want. There is no limit on how many times you can use it within a certain time frame. Also, it really does not matter a home country or any other country. The rule is very simple because in order to be eligible for 144 hour visa free transit all you have to do is to satisfy the requirement that the immediate points before and after your mainland Chinese destination have to be in two different countries or eligible territories (eligible territories: Hong Kong, Taiwan and Macau). In other words, you can use: Stockholm - Beijing - Tokyo, Bangkok - Shanghai - Seoul, Jakarta - Guangzhou - Frankfurt, Paris - Shanghai - Hong Kong or as you wish as long as you are in line with the rule.

Thank you for the answer, much appreciated.
