Why do many foreigners become China fans after working in China?

Many foreigners become China fans after working in China, firstly because:

China people are very hospitable to foreigners. "It's a pleasure to have friends coming from afar." Our tradition since ancient times is warm and friendly, so many foreigners feel at home and naturally become China fans.

In addition, China's ancient culture, such as Peking Opera and Wushu, has a long history and is mysterious, attracting a large number of foreign fans. Out of love for China culture, they fell in love with China.

Also, many foreigners can't stop eating delicious food in China. Hot pot and other delicious food made them feast and began to learn chopsticks.

How can an ancient, mysterious and all-encompassing country like ours not fascinate foreigners?
