There are too many omissions in the answer upstairs. VISHAY's main agents are "Zengyouqiang International" in Taiwan Province Province (with a strange name), Wei Jian International in Taiwan Province Province (with a nice name), General Assembly Group (a combination of several traders), iResearch Electronics and China Power Information. These agents are an echelon of agents, covering almost the supply of components for large enterprises in the mainland terminal market. However, the mainland market is too big, there are many small and medium-sized factories and enterprises, and the procurement relationship is complicated. So there are two, three and four small traders, whose goods are purchased from agents, and the price level is uneven, so there won't be too many goods. Take the vendors in Huaqiang North Market as an example. Fo * * Technology (the company has a certain scale, mostly based on spot, with its own warehouse, samples can be unpacked, and the channels come from major agents in Chinese mainland) and Sheng * * Technology (mostly based on spot, with its own warehouse, the slogan is "One delivery, the channels come from major agents in Chinese mainland", both of which are relatively old spot vendors, and have only recently come out. Mainly based on spot and orders, the channels come from major agents in Chinese mainland and foreign agents). In short, not every agent can get the goods, and it may not be able to get a good price. Traders have their own advantages and customer groups. For example, VISHAY has many categories and application fields, and agency and trade have their own emphases. The most important thing is that there is no product that cannot be sold or bought. Cooperation has a very important relationship with people. As for the choice of suppliers, it depends on the conditions of the enterprise itself.
