我是既高兴又烦恼!高兴的是,河北科禹新型防水材料厂自宣传以来,各地有识之士争相代理,喜讯频传;烦恼的是每一次给李厂长打电话,他不是在接待客户,就是出差在外做工程……我由衷地感受到,找李书民厂长难啊,他实在太忙了! I am happy and annoyed! It is gratifying that since the new waterproof material factory in Hebei Branch Yu has propagandized, people from all over the world are vying to act as proxies; the trouble is that every time I call Mr. Li, he is not at the reception Customer, is doing business on a business trip ... ... I sincerely feel, to find Li Shimin director difficult, he is too busy!
