Why does Yantai have both Lu F and Lu Y license plates?

[VonMaximus]

Here are the specific reasons why Yantai has both Lu F and Lu Y license plates: 1. Newly added plate prefix Lu Y: Yantai introduced the new Lu Y license plate series. This was done because the existing Lu F plate numbers were insufficient due to the large number of vehicles. 2. License plate prefixes of other regions in Shandong Province: Lu A - Jinan, Lu B - Qingdao, Lu C - Zibo, Lu D - Zaozhuang, Lu E - Dongying, Lu F - Yantai, Lu G - Weifang, Lu H - Jining, Lu J - Tai'an, Lu K - Weihai, Lu L - Rizhao, Lu M - Binzhou, Lu N - Dezhou, Lu P - Liaocheng, Lu Q - Linyi, Lu R - Heze, Lu S - Laiwu, Lu U - Qingdao.
