I'm 62 & my husband is 65 year old Malaysian. Can we apply for multiple entry to China?

We are independent travellers who like to visit most part of China. We have visited Guilin, Hangzhou, Tibet, Chengdu & Beijing before. This time around we like to see more & need more time. So we would like to apply for multiple entry and use it to travel to far & wide including Inner Mongolia, Silk Road, Xinjiang & the rest. Thanks
