Seismological Bureao of Guangdong Province,  Guangzhou 510070.       

I thank Dr. Marian C.Mille of editorial department GJSFR very mach, and assent to ask me for offer my some experience of research, I write following: 

1. As go to the practice as possibl. I have went to among the people With the questions of research and paid visit and investigation to the people that they are old fishermanins of sea coast, the old famers in the countrysite, the inhabitants in the city . I get many Informations of seismological calamity situation befor many years and sea level change or coast change condition[1,2,3,4,5] of there not record in script that they told me. I had research  “the sank Dongjing capital city” that is a popular legend in the sea coast of Fujian,Guangdong province of China[5], in the course of the investigation to “the sank Dongjing capital city”,  the paleo-forest about 7500a. BP and the paleo-oyster belt of 25000-15000a.BP exist in the tide belt at the same time today in Shenhuwan Bay of Fujian province of China were discovered by me that were due to above investigation way[5,6,7,8,9].

 2.  Don’t refuse do ordinary and simple thing of geological work, such as observe, take notes and analyse careful on hole core of deposits are ordinary but important. The hole core of deposit have plentiful information on paleo-environment, paleo-geographical features, crustal movement of the place and so on.  I got the experience knows of the sediments of littoral facies have been almost continuous and The sea level changes with gradual advance rising since 45000a.BP[5,10,11,12,13] and the littoral deposits generally have poor permeability and drainage environment within 40 m near the surface or since the middle and Late Pleistocene, the compaction subsidence of littoral deposits is not obvious, therefore, when you conduct the study on paleo-Sea level , coastal crustal movement and paleo- earthquacks in littoral deposits,it is not necessary to take into account the impact of sediment compaction that was owing to that I was careful to observe, take notes and analyse on hole core of deposits[5,14,15]

 3.  Don’t let slip the vague problem that is related to the main research task. Soved the vague problem can shall greatly promote completness of the main research task or can have new find or new important research problem[5,14,15].

 4. Honest, seek truth from facts, matter-of fact attidude that is scientists soul. Face up to fact, have a great esteem for fact that is important pledged of get success step- by- step to researchers, I have did as that conscientious.

 5. Clear The duty and the objective. I am a geological and seismological worker of Guangdong Province of China. I have defined my duty and my research objective of that researth the cause of formation of the paleo-forest about 7500a. BP and the paleo-oyster belt about 25000-15000a. BP of Shenhuwan Bay in Fujian Province of china exist in the tide belt at the same time today after the day of that is since they have been discovered by me in 1986. Because Fujian province and Guangdong province are in common Southeast earthquack belt, I know that the formation of the paleo-forest and the paleo-oyster belt of Shenhuwan Bay exist in the tide belt at the same time today that can relation to the paleo- earthquack and crust movement of Shenhuwan Bay and researth that is importance to know earthquack and crust active feature of south-east coast of China, so that is used my duty and my research objective[5].

 6. Persist in, disregard personal gains and losses
