My Parents Need New Luggage

My parents will be traveling to China for a vacation next month. Winter will be starting soon in China and my parents are going to shop for some winter clothing and new luggage to put their bulky winter clothing. They also intend to bring along an empty luggage to place the herbs and teapot sets that they intend to buy from China. They will be bringing a total of 4 luggage for their trip and I doubt if they can handle so many luggage. I asked them to leave the empty luggage behind. After all, I am really skeptical about products made in China and I told them to just go and enjoy the trip minus the herbs and souvenirs from China.
