Which city is better to find a job, Shenzhen or Beijing, majoring in Russian? Thank you!

If you are a tour guide, maybe Shenzhen is easy to find. Especially in Hainan, it is easier to find a tour guide. Russian is very popular in Sanya. In some places, the store names are in Chinese and Russian, and there are few English ones. Some ordinary supermarket cashiers can understand Russian and have good pronunciation. If it is any other job related to Russian, it should be easier to find a job in Beijing. Mainly because of the high level of foreign languages.
