As it is clear from the figure three circles, denote the three dishes of rice, broth and meat. As two people share the rice dish, therefore I divided it into two equal parts so that each person got half the portion of rice. After that, I divided broth dish into three equal parts as three people share it and each person got 1/3 part of broth. Similarly, I divided the meat dish into four equal parts as four people shared it so that each person got ¼ of meat. Overall, each person got half of rice ,1/3 of broth and ¼ of meat  which is equal to 1/2+1/3+1/4 = 13/12 of the total food of each kind . As there are 65 dishes therefore total number of person who will share 65 dishes =65/13/1.

      Chinese people so far I know are very polite and friendly .I think, the above puzzle also reflects     the same as they are sharing their food as well as their dishes as mentioned. Moreover, this puzzle is from Ancient China fourth CAD, it means sharing food is in their tradition. Hence, there culture makes them more social.
