Chinese bowl, 20thC, faux-Qianlong mark

I have what I think is Vintage Ramen bowls. The have the traditional dragon and the Red Iron Mark on them. I was trying to find out what mark is on the bottom of the bowls? I have 4 bowls. I matched the mark on the bottom of the bowl to what I think might be Qing Dynasty and the period of Ch'ien-lung (1736-1795) I would appreciate any information on these bowls anyone might have. The age, where they are from, value, etc. ???

Thank you!

The mark is 20thC. The characters are copying earlier marks but the numbers show it’s 20thC . You might find the stamp on the Gotheborg website of Chinese Marks . Possibly made in Hong Kong. Production ware with transfer printed decoration.

Thank you NaomiM,
I looked up the link you attached and it appears it is from Qinglong period and made between 1960-90. Thanks again for your help!!!!
