Hadron Physics and QGP 7+35 days, 64 talks + discussion sessionI have participated all the Japan-China symposiums except the first one.2nd China-Japan Joint Nuclear Physics Symposium on Recent Topics of Nuclear Physics, Beijing (China), August 29 September 2, 1994.

3、Talk： ：“ Study of Nuclear Structure and Collisions with Antisymmetrized Molecular Dynamics “.3rd Japan-China Joint Nuclear Physics Symposium, Sendai and Niigata (Japan), July 24 29, 1997.

4、zing Comm., Talk： ：“ Clustering in Neutron-Rich Nuclei ”。 。5th Japan-China Joint Nuclear Physics Symposium, Fukuoka (Japan), March 710 , 2004 Organizing Comm., Session-Chair.Chinese talkers in middle generation (30s and 40s) have increased in number. 10 years ago, Profs. Yu-Gang Ma and Jie Meng were

5、 really young , and Prof. Bao-An Li was working hard in US as a postdoc. Almost no people older than them up to 50s. Now, professors in the same generation as Prof. Ma are leading the nuclear physics communinity of China, and the activity of it is now supported by many young scientists. Maybe, the n

6、umber of talks this time is the largest in this series of symposia. This time the symposium is for 5 days, one day longer than previous ones. It is partly due to the inclusion of the new subject quark hadron physics , but mainly it reflects the increased young activities mainly in the Chinese side.T

7、he umbalance of the number of talkers from China and Japan for thesame subject does not necessarily reflect the umbalance of the number of the actual scientists for that subject. This problem has been present from early time but for me it seems to be reduced this time. My talk is not a summary talk

8、of the 64 talks given here. My talk is to give a concluding ramarks and so my stress may be larger on some selected number of talks, but it does not mean that the others are not worth mentioning with stress.A.
