Dating apps like Momo represent generational shift in attitudes to love
Increasing numbers of mainlanders are using services such as Momo to find sexual partners, but websites seek ways to hook users for longer

Zhang Zhi is a veteran user of Momo, the mainland's "one-night stand app".
Most evenings the 26-year-old software engineer logs on to his account and checks out the women in his area of Beijing.
"Sexy pictures and a clear statement that she needs a boyfriend will easily catch people's eye. A girl like that could get hundreds of messages a day," Zhang said.
"It's difficult for men, though. We have to be not only good looking, but also intelligent and say something to impress girls and gain their trust."
Zhang reads books and plays video games at his flat while he waits for women to respond to his messages.
But he said despite the app's reputation as a way to find casual sex, the key was to woo women with romance.
