"World Tai Chi Day has become an important window for martial arts exchanges between China and the rest of the world. As Chinese kung fu is a cultural tie that links China and the world, I would like to send my kids to the China Culture Center in Benin, where they can know more about Chinese culture by learning Chinese language and martial arts," Ortega said during an interview after the event.

"Martial arts are popular in Benin and the China Culture Center in Benin has been committed to popularizing tai chi here since its founding in 1988. The 2018 World Tai Chi Day in Benin is the first and the largest of its kind in the country to promote the exchanges of martial arts. By doing so, we want to help the Beninese better know about Chinese kung fu and deepen the friendship between the people of the two countries," Wei said during the interview.

World Tai Chi Day, which falls on the last Saturday of April every year, is an event celebrated by tai chi buffs in hundreds of cities around the world.
