Walkie talkie, can that be used in China?A friend lived in a remote rural area got handicapped so I think a walkie talkie will be a handy gift. I have found a few candidates, like this one, http://www.sz-haiyun.com/products.htm but I am concerned with whether this device is legal for use in China? Do I need to buy a license? (Though in that county nobody will likely find out that he has such device)
