Is morning light milk only available in Shenzhen?

No. Chen Guang Milk is produced in Chen Guang Dairy and is headquartered in Shenzhen. It is a large-scale fresh milk export enterprise in China, and Chenguang milk has gone from Shenzhen to the international market. Its products account for 90% of the fresh milk market in Shenzhen and 40% of the fresh milk market in Hong Kong, and are also exported to Vietnam, Malaysia and other countries. So morning milk is not only available in Shenzhen.
