Asked which is tougher, being a mom or being a boxer, Huang said it's no contest. 

"Boxing is very tough, but you train for it. It takes a long time, but you train and get better. There's no training for being a mom. It's something you have to learn very quickly. There's no time to really think about it ... you just love your child and do the very best you can."

Saturday's card was the second stop of the IBF Silk Road Champions tournament, which kicked off its second edition in Macao in August. 

Last year the IBF became the first global sports organization to integrate the Chinese government's Belt and Road Initiative into a highprofile competition series, incorporating the 60-plus nations in Asia, Africa, the Middle East and Europe that are participating in the Silk Road Economic Belt and 21st Century Maritime Silk Road. 

"We created a ratings system that allows fighters to be assessed by the B&R ranking committee and is published quarterly," said IBF president Daryl Peoples. 

"The champions and top contenders from each country are listed by division and qualify for our world rankings. 

"Our aim is to use the annual tournament to stimulate boxing's growth throughout the region by providing a platform for fighters to develop their pro careers and for promoters to produce quality events for the fans. 

"We're in it for the long haul. And in the spirit of President Xi's desire to foster harmony among the nations participating in the Belt and Road, we hope to eventually expand beyond boxing and embrace other sports and social initiatives in the participating countries."
