Excellent trip arranged by Rita Jiang from China Discovery (Chendu). The selection of guides were the best we had so far in our many travels to China. Jenny (Beijing) and Celina (Harbin) were uncompromising in ensuring that we, as senior citizens were comfortable and not stressed in any way. We had no issue too with paying 100% of the tour price on the first day though we had initial doubts. No hesitation in recommending Rita, Jenny and Celina and China Discovery (Chendu).
