Secondly, at present, there is no professional Rubik's Cube Club in Xi 'an, and there are no professional Rubik's Cube sales with more than 4 orders (Xinhua Bookstore has 4 Rubik's Cube, but the price is very high);
Third, Xi 'an's third-order Rubik's Cube wholesale market is on the ground floor of Daniu Mall next to Kangfu Road. The quality varies, but you can find one with good quality and very cheap price.
Finally, some universities have Rubik's cube interest groups, but they are limited to simple Rubik's cubes of order 3 and 4. You can ask about them. Before 2004, there was an interest group in Jiaotong University. I wonder if there is one now. Want to buy a professional Rubik's cube, Taobao has it!
I hope it helps you:)
