I think for gift item, Yiwu is the good place to check the market, you can find every gift items their in low price. Their quality is ok,you cannot expect much. You can also come to guangzhou, or shenzhen, there are some gift show going on in early April. So you can compare which area is better for you.

PLEASE LET ME KNOW WHICH ROUTE TO BE TAKEN? FROM INDIA WHICH CITY SHOULD I LAND FIRST AND THEN CARRY ON TO OTHER CITIES THROUGH WHICH MODE OF TRANSPORT?

Well, I think you could fly to Guangzhou, or HK directly from Indian. Then, both of the express train and bus could be used for transport between cities.
