I can't help but sigh at how fast time flies, and before we know it, 2011 has already arrived. Calculating from when I first came into contact with Taobao until now, it's been more than two years. In these two years, I've witnessed tremendous changes in Taobao, and I constantly feel the inadequacy of my own knowledge. Personally, I feel that this industry related to Taobao is relatively new; there’s hardly any experience left by predecessors, so we can only rely on ourselves to try and explore more. Therefore, it can be quite tiring. Without further ado, I'll share a few questions, which could also be related to Taobao optimization! I hope they will provoke everyone's thoughts.
