There is an Ebay dealer in Hilpoltstein, Germany (asienlifestyle888) who also sells Chinese racing/rally car fake plates. He has some with different ideograms on them but they are all from the same manufacturers of fake souvenir plates in China.
None of these are real and all are just cheap souvenirs for your donkey cart.
I have been told the ideograms on 2888 and 3888 mean “get insurance” whilst 1888 has “extreme speed” and 0888 has “cross country”.
Cheap souvenirs to part you from your money. Not vehicle licence plates at all.
These are just some of the many different serial numbers he sells and there are many of each number.
