Need Work Visa or not if I only need to work in China for 14 days each time

Hi,

I'm going to be employed by a Chinese company that will need me to pay taxes in China.

My new work requires me to travel to China a few times a year but I won't be staying past 14 days each time.

I will still be mainly residing in my country.

Will I still require a Z or any other documentations?

Thanks a lot!
