Can you telle if this is correct? There is no postal code. Also do I have to write the mobile number on the address label? I've been asked to return an item to; CHEN CHUCHU RIGHT SIDE OF THE 1ST FLOOR MINGMEN LISA LEATHER FACTORY LUOGANGQI ROAD EAST ROAD JUNHE STREET BAIYAN DISTRICT GUANGZHOU CITY GUANGDONG PROVINCE
You should also add the District in the address.
It should be Jiankang Road, Qinghe District, Huaian City, Jiangsu Province
