what a nice person you are! thanks for those books recommended by you, but from the titile, i know it is impossible for me to get them in China, besides, they are written in German, my German is not good enough to read them, especially in Academic books.
thanks anyway, but i will try those links.
sorry i made a mistake that i took you as a German for granted,
but Germany can be said your second hometowm, right?best wishes,
