Methods The capture-recapture method was used to investigate 20 MSM sites in Shenzhen to estimate the number of MSM populations. Results A total of 2 982 MSMs were acquired in the two surveys, the first of which was 1 577 and the second 1 405 were marked with 312 markers. The estimated total number of MSM sites is 6 468 ~ 7 706. Qualitative interviews with 1 577 insiders, MSM crowd and place owners estimated that there are 100,000 to 200,000 MSM in Shenzhen.
