Loong Air is a Chinese airline operating passenger and cargo flights. This is a 4K livery.
Unzip the file Asobo_A320_NEO_CDC_LoongAir.zip file, and then copy the folder Asobo_A320_NEO_CDC_LoongAir into the Community folder of Flight Simulator 2020.
Note that some of the Loong Air flights are not flyable in the simulator as the airports of the flights are not included in the scenery.
An example of a flyable Loong Air flight is GJ8561 from Xi'an (ZLXY) to Baotou (ZBOW).
P.S.
I want to add the Chinese airline name on the bottom of the wing, but after I added it on the left wing, the right wing has the name flipped horizontally, as two wings are mapped to the same part of the texture. If someone know how to fix it, please let me know.
