Hotels, event planners, cake bakers and dress makers are eying up the wedding market, which is expected to boom as a generation of Chinese born in the 1980s and 1990s look to tie the knot.

Public data showed the country's annual spend on marriage ceremonies was 400 billion yuan ($64.3 billion), about 2.5 percent of GDP.

The figure is just the tip of the iceberg as the wedding sector is a sunrise industry, expected to grow rapidly in coming years.
