The ones from Huaqiang Group and SEG Group are very expensive.

The following is a reference:

Huaqiang Electronic World, just outside Exit A of the subway station, a counter on the third floor costs more than 7,000.

The counter on the 6th floor of SEG is also more than 7,000, and the ones on the 1st to 5th floors are even more expensive.

Jiahe Phase 3 is cheaper, 2000 at the small counter on the 3rd floor.
