Help with Chinese seal on old(?) painting

I found this at my local thrift store this morning. It looks nice, but what made me want to fjnd out more about it was how heavy it is for only being 27" H x 21" W ? Also the wood appears to be black; could it be ironwood (I think thats the name - I've had African statues with dark wood & heavy weight and I think that's what it was called)? - it also has small spaces with a solid wood all along the frame - ebony, maybe?
And on the back it shows someone had it professionally framed and paid for uv protection glass.
Can anyone tell who the artist is?
Any ideas or thoughts on the painting and/or frame?
Thank you !

 

Charming painting, it is Korean, as is the seal. Looks like a village festival.

 

Here's the same scene, but with a different seal, saying it's Chinese

And here's the same scene
https://www.rubylane.com/item/1356998-1583/Korean-Village-Celebration-Festival-Asian-Watercolor and now it's Korean


And Google Lens shows another one, linking to a page on a Kenyan site, with Japanese text, but the site isn't working... But the text that's visible with Lens, translates to: Reproduction: Korean Art, Korea, Yi Ju-seok, Genres, Paper, Hanging Scroll, Framed

 

The Ruby Lane seller is right. The people are dressed in Korean 'hanbok'.

 

Traditional Korean hanbok, the woman on the right in the green skirt is wearing one of these:



There are a few men dressed like this in the background, also Korean hanbok:

 

According to Google, the text on the banner is in Chinese, and it translates to:
Agriculture is the foundation of the world

 

That is the thing with East Asian characters. Google probably can't tell the difference between Korean, Chinese, or Japanese. They look the same when written, because characters are symbols. However, it sounds differently in all three languages. In this case Korean.

 

Gotta love the grandiosity of that!

 

Any idea who the artist of mine was?
Some of the brush strokes on the trees look lkke watercolor?

 

Same seals on these Korean themed artworks.

One of my personal 'household' gods is the honey bee.I put 'em right up there w/ all the big invisible male deities in the sky (maybe even a sliver above).
PS-Recent history lesson re: going to war w/ nature-Chairman Mao's 1958 campaign to exterminate sparrows as part of the broader "Four Pests" campaign.

 

Based on what Marote found, the artist may be Yi Ju-seok.

 

Thank you - and thank you everyone!
