, Sunroom; Searching for purchase information of related products on Alibaba is undoubtedly a daily must-do task for every online marketing friend, and I am no exception. This matter actually started a few days ago when I entered the supply webpage by searching for "dotting machine". The first result was from a Shenzhen customer who is an integrity pass user in the plastic products industry looking to purchase an automatic dotting machine. Although I am not an integrity pass user, I asked a friend to help me find his Tradewind contact details, and then I sent a message to Manager Lü asking if there was still demand for the automatic dotting machine. He replied after about ten minutes saying that there was still demand, but he had just stepped out. He mentioned that he was involved in making rubber stamps and asked if I understood this field or not. I was momentarily confused and forwarded the situation to my boss. However, since my boss was not near the computer, he did not reply. Later, I sent a few more messages, but Manager Lü did not respond afterward. I thought of giving up at that point because automatic dotting machines are somewhat complex, and I do not know much about them, which makes selling them relatively difficult. That afternoon, I remembered a manager from a similar company whom I met not long ago on Trade Assurance. We both share the surname Liu, and we chatted very well. He also taught me things I didn't understand. Moreover, he mainly deals with automatic dotting machines, so I thought it would be better to pass the information to him and let him follow up. The next morning, Manager Liu told me that the customer might not want to buy the dotting machine but instead wanted to obtain some technical data. I thought this matter would end here and did not think too much about it because not every inquiry on the internet will succeed! (To be continued) , Color steel plate; , Art district; , Punch press; &
