Flight requires me to collect baggage in TFU

Sama, you did not mention your flight itinerary, so it is almost impossible to determine your eligibility for visa free transit scheme. OK, in case if you are flying via China between two different countries and your total transit time in China is shorter than 24 hours, then you are eligible for 24 hour visa free transit and you do not need any kind of visa. .

Upon landing in Changsha, the first thing you will do is to approach 24/144 hour visa free transit where you will apply for a temporary entry permit in order to be allowed to exit the transit area since you will have to collect your luggage and perform new check-in. This application is free of any charge and here you will present your flight tickets. After a short check, you will be granted a temporary entry permit and you will head to the immigration in order to collect your luggage and to perform new check-in.

After you have done this formality, you will again head to the immigration and proceed to your onward flight that will take you out of China. Have a nice journey.
