Photography exchange, photo sharing, digital product evaluation, Zhongguancun online or Pacific Ocean is better (including the speed of webpage opening and the number of advertisements).

Product evaluation is not easy to compare because of different emphasis. Zhongguancun Online generally evaluates more digital products, while Pacific generally evaluates the performance of computers (motherboards, graphics cards, cups, etc. ) more, so it is the same as saying that steamed bread is delicious or pancakes are delicious. Everyone has different preferences. If you want to save a computer yourself, then if you want to know about digital products, go to the Pacific Ocean and take a walk in Zhongguancun. If you ask about the opening speed of web pages, this will be tested by professional software, because we generally don't care too much about this, and the difference in their opening speed should be calculated in thousands, so we generally don't feel it. I hope it helps you.
