You may find shops for international top brands (same prices as international standard), a Wanda Shopping Mall and a Wal-Mart's supermarket among others.
There are Chinese souveniers at the retail outlets in these shops, and also Russian-imported goods shops are also found in the popular districts of Changchun as well as all over Northeast China major cities, such as Shenyang, Harbin and Dalian. The typical items for sale here are: 1) Matryoshka Nesting Dolls, 2) Lenses such as binoculars or telescopes or reading lenses, 3) Russian-style pink gold jewellry and watches, 4) Assorted sundries, such as pen-knives, pewter items, etc., and 5) carved jadework (simulated jade?) in shapes such as a bok-choy lettuce, and other traditional shapes. Anyway, of these items are more or less affordable quality.
This is a tip if you live actually in town, because a tourist will never be interested in a place where you can buy good quality meat.
Well, this is the best place to buy meat for barbecue or for daily homecook meals...
The Ouya - or Eurasia - department store is one of the biggest and most crowded stores in Changchun.
There you find whatever you may want, from clothes to computers and electronics on the highest floors.
What to pay: This department store does not accept credit cards, just cash!
As anywhere in Chine, there is a place, where you can buy counterfeited clothes. They are cheap, if you can haggle about the prices, and of quite good quality.
This mall near home is one of the nicest malls in town.
Besides the various shops, there is also a small supermaket with some imported goods and a McDonald's (for those homesick).
