i need to travel from (Guangzhou Baiyun International Airport) to (Jiaxiye Plaza, NO.318, Minzhi Boulevard, Longhua new District, Shenzhen,518131,China) by metro or bus

You can take the airport shuttle bus to reach Bagualing in Shenzhen. Then take a taxi to reach Lianhua North Station of local subway Longhua Line and then you can take this line to reach North Railway Station where you can change to Huanzhong Line to reach Minzhi Station. Get out of the station and then walk along Minzhi Avenue to Boulevard to reach that plaza.
