Moments after registering their marriage, Zhang Gang and Weng Linbin posed in front of a red backdrop adorned with a Chinese government emblem, fanning out the wad of cash they had received as an incentive to wed.

Zhang's home city of Luliang in northern Shanxi province is one of many places in China where local authorities are offering a slew of inducements to coax couples into tying the knot.

The 1,500 yuan (HK$1,600) reward the couple received is part of official efforts to boost the country's population, which fell for the third straight year in 2024.

The sum is half a month's average wage for Luliang's urban population - and more than the monthly average wage for its rural citizens, according to official data.

"I think this policy is quite effective in improving the current marital and romantic situation," Zhang said.

"When I mentioned this policy to my friends, they all thought it was great."

More generally, though, authorities are fighting a tide of reluctance from young people.

Last year marriages dropped by a fifth compared to 2023, data showed.

When Luliang's cash incentive for marriage was announced online, many commented that the amount wouldn't be enough to justify the commitment.

The reward - which has an age cut-off of 35 for women - is just the flashiest part of the package.

The former mining city is also offering subsidies and medical insurance contributions for registering newborns. Married couples in Luliang are given 2,000 yuan for their first registered child, 5,000 for their second and 8,000 for their third.
