Hainan Tang Yi Handicraft Factory, opposite Aihua Automobile Plaza on Haikou Binhai Avenue, is on the roadside. There are many buses that can go directly and the transportation is convenient.
Haikou Ocean World Handicraft Factory is located in an old courtyard on Erheng Road, Longhua. There is no direct bus here, but you can take a private car (commonly known as motorcycle) or a taxi to the factory, which is not easy to find. Give them a call before you leave and see if you can send someone to pick you up.
Hainan Perfect Company, in Lantian Road, can be reached by many buses, but the products are a little less, and the price seems to be a little higher than the first two, but it doesn't matter if you can't get many goods;
By the way, there are many companies online that are deceptive. Basically, they take orders from the internet and then purchase goods outside.
If you want to purchase goods, I suggest you take them on the spot, which is more secure. Don't trust online propaganda. There are too many holidays these days, so you must read them and believe them!
