I think the influence of Chinese culture has been significantly shaped by geography. As you can see, it has covered the entirety of mainland China, extended as far as possible to the east by encompassing the Korean Peninsula and even Japan. In the east, geographical barriers are easily noticeable—they serve as both geographical and cultural boundaries. Moving further south, Vietnam appears to be the final frontier, often considered the dividing line between Chinese and Indian cultures.

Eight is enough. Over 20% population of world.

Chinese:😐-->😠

East Asian culture sphere would be more appropriate.

Taiwan is an independent country and does not belong to the People's Republic of China. The People's Republic of China has expanded its armaments for many years to prepare for the invasion of Taiwan. The People's Republic of China is trying to invade Taiwan and make Taiwan a part of it. The new axis of evil led by Russia, the People's Republic of China, North Korea and Iran has taken shape. They are destroying our democracy and freedom. antichinazi

🇹🇼this is real CHINA!

可不可以不要丟人現眼！ sinosphere: 漢字文化圈。 你不會看地圖把日本和韓國都列入了喔。有夠白癡的青鳥。 Please go check the definition of sinosphere. Obviously, Taiwan speaks mandarin, and use traditional Chinese. This is not a post about Taiwan‘ sovereignty.

I count 5? Unless you use a different definition for "nation"
