I got postcard from Greetings from series from China after long time. It shows some basic facts about China, but too little to be honest, and not so good selection of data. For example, there's no mention of The Great Wall of China.
Three nice stamps at the back:
Vacation Activities, issued on 19.5.2015. Conservation of water, issued on 1.4.2002. Pineapple from set Fruits (Series 3), issued on 14.7.2018.
