Large Chinese Signed Porcelain Ginger/Temple Jar

I recently bought a Chinese ginger/temple jar at a car boot, but have been unable to
locate the Made in China signature on Gothenburg's website.

Would appreciate any assistance as to approximate age, but would say it looks pretty modern

 

All if the Made In China marks were used well into the 20th century- post WWII to 2000 at least. The one example Gotheborg shows that includes the line of Chinese characters for the phrase is dated in the late 20th. I doubt that having been stamped in red ink instead of blue makes any difference in general age or value. Your "looks pretty modern" is as close as you're going to get.
