n Back from Shanghai, the most impressive thing when performing any experiments is the low efficiency and high cost. Take reagents for example, sigma provides special discount to labs in SIBS (at least 20%off). In contrast, all reagents ordered in Chongqing are priced twice as much. What's more, if the price for some reagent is 60 dollars, then we have to pay more than 600 RMB, sometimes, 900RMB.  In addition to that, we have to wait 6-8 weeks before any information of its arrivial comes, compared with 2-4weeks in Shanghai. This is exausting!
